Pressure in a liquid increases with depth give reason

Variation of Pressure with Depth in a Fluid Physic

  1. Under water, the pressure exerted on you increases with increasing depth. In this case, the pressure being exerted upon you is a result of both the weight of water above you and that of the atmosphere above you
  2. The jet of water from the lowest hole travels the farthest because the pressure exerted by the water column is the highest at this point. From the distance travelled by the four jets, you should be able to guess that the pressure exerted by the water increases as depth increases
  3. But as we go we deeper in a liquid the pressure of liquid increases.As the depth of liquid increases the weight of liquid column pushing down from above increases and hence the pressure also increases. please mark as brainliest...plz plz plz New questions in Physic

Pressure increases with depthAn Introduction: The pressure exerted by a liquid increase with depth A liquid exerts the same pressure in all directions at a.. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus a column of fluid, or an object submerged in the fluid, experiences greater pressure at the bottom of the column than at the top. This difference in pressure results in a net force that tends to accelerate an object upwards. (12 votes The liquid exerts pressure on the base of the vessel. The pressure exerted by a liquid changes with depth in the liquid. The pressure exerted by a liquid increases with increasing depth inside the liquid. The pressure exerted by a liquid is small just under the surface of the liquid

The reason is that the pressure exerted by a liquid increases with its depth. A thicker wall is required to withstand a greater pressure and therefore the wall of the dam is made with thickness increasing towards the base. The sea divers need special protective suit to wear because in deep sea, the total pressure exerted on th because it depends on height only in static conditions. force acting at a horizontal level is product of pressure *area which is due to weight above not below (its like u take 3 boxes five kg each and place them in a stack one above other, the low.. You will find that water comes out with greater force from the holes at greater depth. Water from the bottom-most hole will be spurted out the farthest from the container. This shows that the pressure in a liquid increases with increasing depth

Pressure: How is the Pressure in a Liquid related to depth

  1. increases with depth The pressure in a liquid depends on three things: (a) the depth within the liquid (measured vertically from its surface) (b) the density of the liquid (assumed uniform
  2. Hydrostatic pressure increases in proportion to depth measured from the surface because of the increasing weight of fluid exerting downward force from above. If a fluid is within a container then the depth of an object placed in that fluid can be measured. The deeper the object is placed in the fluid, the more pressure it experiences
  3. The pressure exerted by a liquid increases with its depth. Thus as depth increases, more and more pressure is exerted by water on wall of the dam. A thicker wall is required to withstand greater pressure, therefore, the thickness of the wall of dam increases towards the bottom. Question 2

Pressure within a liquid depends only on the density of the liquid, the acceleration due to gravity, and the depth within the liquid. The pressure exerted by such a static liquid increases linearly with increasing depth Similarly, if more pressure is applied to the liquid, force of attraction increases so that the liquid is converts into solid state. As the pressure increases the rate of crystallization also increases. i.e., the freezing point also increases This is because the pressure in a liquid increases as you go further below the surface of the liquid. A common example in exams is this - a can full of water with holes down the sides. Notice how the further down the hole is, the faster the water comes out because the higher the pressure is in that part of the can The reason it does not affect you is that your internal body pressure increases to neutralize most of the water pressure. But at greater depths, the water pressure can become so great that it can harm the diver. Demonstration with can. A demonstration of how water pressure increases with the depth of the water can be done with a large tin can

Pressure increases with depth - YouTub

Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.: 445 Gauge pressure (also spelled gage pressure) is the pressure relative to the ambient pressure.. Various units are used to express pressure. Some of these derive from a unit of force divided by a unit of area; the SI unit of pressure, the pascal (Pa. As you go deeper into a body of water, there is more water above, and therefore a greater weight pushing down. This is the reason water pressure increases with depth. The pressure depends only upon the depth, and is the same anywhere at a given depth and in every direction What happens to the pressure exerted by a liquid when the depth of the container increases? Give reason. 1 See answer But as we go we deeper in a liquid the pressure of liquid increases.As the depth of liquid increases the weight of liquid column pushing down from above increases and hence the pressure also increases. please mark as. As the temperature of a liquid or solid increases its vapor pressure also increases. Conversely, vapor pressure decreases as the temperature decreases. The vapor pressure of a liquid can be measured in a variety of ways. A simple measurement involves injecting a little of the liquid into a closed flask connected to a manometer Fluid pressure is a measurement of the force per unit area.Fluid pressure can be caused by gravity, acceleration, or forces in a closed container. Since a fluid has no definite shape, its pressure applies in all directions. Fluid pressure can also be amplified through hydraulic mechanisms and changes with the velocity of the fluid.. In a fluid column, as the depth increases, the pressure.

To find the pressure at the bottom of a column of liquid of density ρ, height H and area A, consider the diagram below: Volume of liquid: V = HA Density of liquid, ρ, so its mass: m = Vρ = HAρ A H Thus the pressure exerted by the liquid is P = weight area = mg A = HAρg A = Hρg where g = 9.8ms−2 is the acceleration due to gravity. Note. Liquid Level Measurement A pressure transmitter can be used to determine the liquid level in a tank, well, river or other body of liquid. The pressure at the bottom of a liquid filled container is directly related to the height of the liquid. The transmitter measures this hydrostatic head pressure and gives the resulting liquid level

Pascal's principle, also called Pascal's law, in fluid (gas or liquid) mechanics, statement that, in a fluid at rest in a closed container, a pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the container. The principle was first enunciated by the French scientist Blaise Pascal.. Pressure is equal to the force divided by the area on. Q29) Describe a simple experiment to show that at a given depth, a liquid exerts same pressure in all directions. Q30) State two factors on which the pressure at a point in a liquid depends. Q31) Describe an experiment to show that the liquid pressure at a point increases with the increase in height of the liquid column above that point As the temperature of a solid, liquid or gas increases, the particles move more rapidly. As the temperature falls, the particles slow down. If a liquid is cooled sufficiently, it forms a solid. If a liquid is heated sufficiently, it forms a gas. Pressure Effects Changes in presure have very little effect on the volume of a liquid The force comes from the difference in pressure exerted on the top and bottom of an object. For a floating object, the top surface is at atmospheric pressure, while the bottom surface is at a higher pressure because it is in contact with the fluid at a particular depth in the fluid, and pressure increases with depth

Let's use Equation 14.9 to work out a formula for the pressure at a depth h from the surface in a tank of a liquid such as water, where the density of the liquid can be taken to be constant. We need to integrate Equation 14.9 from. y = 0, y = 0, where the pressure is atmospheric pressure. ( p 0), ( p 0), to For each meter (foot) increase in depth, the swimmer is subjected to an increase in pressure of 9,810 N per sq m (62.4 lb per sq ft), because water weighs 9,810 N per cu m (62.4 lb per cu ft). Since a liquid is nearly incompressible, its density does not change significantly with increasing depth. Therefore, the increase in pressure is caused. Pressure increase with depth • The deeper into a liquid you go, the greater the weight of liquid above and the higher pressure. Pressure 70 71. Pressure depends on the density of the liquid • The more dense the liquid, the higher the pressure at any particular depth. Pressure 71 72

Laws of liquid pressure: (i) Pressure at a point inside the liquid increases with the depth from its free surface. (ii) In a stationary liquid, pressure is same at all points on a horizontal plane. (iii) Pressure is same in all directions about a point in the liquid. (iv) Pressure at same depth is different in different liquids Pressure. The force acting perpendicularly on a surface is called the thrust. Pressure is defined as the thrust on unit area of a surface. Its SI unit is Newton. Its SI unit is Pascal. 3. a. Ans: Foundation of buildings is made wider than the walls because pressure is greater in the depth of the building in the diagram below you can seee that as depth increases the pressure (which is measured in bar increases. Therefore a diver at 30m, which is the depth a qualified open water dive can descent to, will be under 4 bar of pressure. The 4 bar comes from 1 bar from the weight of the atmosphere and the 3bar from the weight of the water above him If the pressure decreases then the valve is closed to allow the pressure to build back up again. Notice, however, that both these actions will have an effect on the level of liquid in the tank. If the pressure decreases then more liquid will vapourise and the level will decrease. If the pressure increases then the level will rise

An interesting variation on this theme of direct hydrostatic pressure measurement is the use of a purge gas to measure hydrostatic pressure in a liquid-containing vessel. This eliminates the need for direct contact of the process liquid against the pressure-sensing element, which can be advantageous if the process liquid is corrosive > Q: Why does atmospheric pressure always decrease with altitude? Because in a gas, temperature is the average speed of the molecules, and pressure is how closely they are packed. In a vacuum, all molecules will eventually fly off into the void,. 2. Pressure at a certain depth in water. Scuba divers know that as you go down to greater depths, the water pressure increases. In fact, the increase in pressure is 14.7 psi for every 34 feet of additional depth. A diver that descends to a depth of 100 feet must withstand a pressure of ( 100 ft / 34 ) x 14.7 = 43.24 ps Note: It is important to read the introductory page about thin layer chromatography before you continue with this one - particularly the part about how thin layer chromatography works. High performance liquid chromatography works on the same basic principle. HPLC is essentially an adaptation of column chromatography - so it might be a good idea to have a (very quick) look at that as well The pressure at a point in a liquid is the same in all directions - upwards, downwards and sideways. It increases with the depth inside the liquid. When a body is immersed in a liquid, the thrusts acting on the side walls of the body are neutralized as they are equal in magnitude and opposite in direction

PRESSURE AND TEMPERATURE RELATIONSHIP. In a closed system where volume is held constant, there is a direct relationship between Pressure and Temperature. In a direct relationship, one variable follows the same change when it comes to increasing and decreasing. For example, when the pressure increases then the temperature also increases Even though it is very hot, these materials don't melt very easily, so they stay solid. Answer 3: It turns out that many materials can be a solid at a higher temperature if the pressure is also higher. So, even though it is hotter in the inner core, the pressure in the core is also higher, and you can have solid iron-nickel instead of liquid pressure under 5 meters of water in a big swimming pool. This is why water always seeks a constant level. The pressure at any uniform height in a single liquid is the same throughout the entire liquid. In addition, if the outside, or external pressure increases, the total pressure increases by the same amount. Pascal realized that this led to. Depth Filtration Mechanisms.. 688 2.4.2.

Figure 5-5. A uniform open-channel flow: the depth and the velocity profile is the same at all sections along the flow. 12 One kind of problem that is associated with uniform flow is what the channel slope will be if discharge Q, water depth d, and bed sediment size D are specified or imposed upon the flow Hills, Valleys, & Slopes: Consider the slope or you'll look like a dope! Elevation changes can add or subtract water pressure from your water system. That seriously changes how well the system works. Each foot of elevation change is equal to 0.433 PSI of water pressure. Think of a vertical column of water. At the Continue reading Elevation Pressure Loss in Irrigation Systems Formula and Unit of Pressure. Pressure (P) = Thrust/ Area. The SI unit is 'pascals (Pa)'. 1 Pa = 1N/m 2. Example: It is easier to hammer a sharp pin than to hammer a blunt pin. This is because the area at the end of the sharp pin is smaller than the area at the end of a blunt pin. This leads to an increase in pressure leading to hammer the. In downhill lines, flow becomes stratified as liquid flows faster than gas. The depth of the liquid layer adjusts to the static pressure head and is equal to the friction pressure drop. There is no pressure recovery in the downhill line. In low gas/liquid flow, the flow in uphill segments can be liquid full at low flow rates

Pressure Exerted by Liquids Class 8, Force and pressur

The buoyant force doesn't depend on the overall depth of the object submerged. In other words, as long as the object is fully submerged, bringing it to a deeper and deeper depth will not change the buoyant force. This might seem strange since the pressure gets larger as you descend to deeper depths Pressure in the Deep. Everything in the deep ocean is under a great deal of pressure. At any depth in the ocean, the weight of the water above pushes on any object below it. With every foot an object descends into the ocean, more water is pushing down and against it, and more pressure is exerted upon that object Due to this reason, the atmospheric pressure at a height of about 6 km decreases to nearly half of its value at sea level. (c) Since due to the applied force on the liquid, according to Pascal's law, the pressure is transmitted equally in all directions inside the liquid. Thus there is no fixed direction for the pressure due to liquid The vapor pressure of liquid substance is the partial pressure due to the particles of that substance which have enough kinetic energy to overcome the cohesive forces near the surface of the liquid and enter the gas phase and form a vapor. The moment a chemical entity enters the gas phase it can hit the surface and condense back into the liquid. For horizontal plane submerged in a liquid, the pressure, P, will be equal at all points of the surface. This leads to the conclusion that the resultant force on horizontal surface due to that pressure can be computed from the simple product of pressure times the area of interest, i.e

A: Greater Than, A has a larger surface area on the bottom, and thus has a larger force since pressure is the same because they have the same depth. B: Equal To, pressure is just related to depth. Since they all have the same depth, the pressures are equal. C: False, water does not come in contact vertically with the tank Analysis Since pressure increases with depth, the pressure on the bottom face of the cube is higher than that on the top. The pressure varies linearly along the side faces. However, if the lengths of the sides of the tiny cube suspended in water by a string are very small, the magnitudes of the pressures on all sides of the cube are nearly the.

Bubble formation deeper in the liquid requires a higher pressure, and therefore higher temperature, because the fluid pressure increases above the atmospheric pressure as the depth increases. More pertinent to low-boiling hydrocarbon mixtures such as condensate, the vapor pressure that a single component in the mixture contributes to the total. The pressure in a fluid increases with depth. The reading of blood pressure on the sphygmomanometer when the measurement is made at the leg is greater than the measurement is made on the arm. This is due to the reason that the leg of the standing person is below the heart level (or arm). Chapter 15 Fluids Q.82G Increasing the pressure in gas-liquid reactions increases the solubility of the gas in the liquid which increases the reaction rate. Reaction Phase. Reactions are usually carried out in liquid or gas phases as fluids are easier to handle, heat and cool, and transport than solids

Production of fluid from a reservoir starting at point B in Fig. 1 causes liquid to appear in the reservoir when the dewpoint pressure is reached. As the pressure declines further, the saturation of liquid increases because of retrograde condensation. Because the saturation of liquid is low, only the vapor phase flows to producing wells 4) The pressure at the bottom of a jug filled with water does NOT depend on the _____. A) depth of the liquid B) density of water C) surface area of the water D) acceleration due to gravity E) none of the abov With increases in pressure and temperature, coal seams form. Several different types of coal can be found depending on the depth and location of the seam. The four main types of coal, which differ by carbon content are shown in the following table Hot water pressure increase in a heating boiler: As a point of reference, in a residential hydronic heating boiler we actually observe an internal water pressure rise from 12 psi cold up to 28 psi hot as the boiler temperature increases from perhaps 60 °F up to 180 °F anced by an increase in pressure (Fig. 3-5). To obtain a relation for the variation of pressure with depth, consider a rectangular fluid element of height z, length x, and unit depth (into the page) in equilibrium, as shown in Fig. 3-6. Assuming the density of the fluid rto be constant, a force balance in the vertical z-direction gives (3-6

Hydrostatic pressure is the pressure that is generated by the weight of liquid above a measurement point, when the liquid is at rest. The height of a liquid column, of uniform density, is directly proportional to the hydrostatic pressure. The hydrostatic properties of a liquid are not constant and the main factors influencing it are the density. This treatment reverses the pressure changes that allowed gas bubbles to form in the blood stream. The treatment drives nitrogen back into its liquid form so that it can be cleared more gradually from the body over a period of hours. It is not recommended that divers with decompression sickness attempt to treat themselves with deep diving The pressure of the liquid (blood) forces the liquid to move into the syringe when its plunger is withdrawn. When air is sucked out of a drinking straw, the air pressure inside if decreases and the atmospheric pressure outside forces the liquid to go inside the straw. Skis have a large area to reduce the pressure on the snow Further, the mean free path (or the average distance a molecule must travel before colliding with another molecule) increases greatly as the pressure decreases (Fig. 2). Most importantly, the increased mean free path at reduced pressure dictates that molecular collisions with the vessel walls govern the gas properties at reduced pressure

What are the applications of liquid pressure? - Quor

Rearranging and solving gives: V 2 = 0.300 L×303 K 283 K = 0.321 L V 2 = 0.300 L × 303 K 283 K = 0.321 L. This answer supports our expectation from Charles's law, namely, that raising the gas temperature (from 283 K to 303 K) at a constant pressure will yield an increase in its volume (from 0.300 L to 0.321 L) At sea level, this can also be stated in terms of 29.94 inches of mercury (barometers) or 33.9 feet of water. Hence, at sea level we can say that a tank has 14.7 psia of pressure on it from atmospheric pressure or we can say that it has 33.9 Feet of Head. The convention with centrifugals is measure pressure in Feet of Head Note that z is defined as zero at the surface, so pressure increases with depth (since z < 0 under water) with a constant slope, ρg. Pressure is either considered relative to a reference pressure or in absolute terms. Most pressure gauges are differential measurement devices that measure pressure relative to ambient (or atmospheric) pressure If you ever drop your keys into a river of molten lava, let 'em go, because, man, they're gone. -Jack Handey Take a look at our home planet, Earth, and one of the things you'll notice is that. The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure.It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer.In a barometer, a column of mercury in a glass tube rises or falls as the weight of the atmosphere changes

It is also important to figure out the pressure under water or in a liquid. The pressure under water increases with how deep you are. The equation for calculating pressure under a liquid is: Pressure = D * g * h. where D is the fluid's density, g is a standard gravity (9.8 m/s 2), and h is the depth of the object in the liquid Above every square inch on the surface of the Earth is 14.7 pounds of air. That means air exerts 14.7 pounds per square inch (psi) of pressure at Earth's surface. High in the atmosphere, air pressure decreases. With fewer air molecules above, there is less pressure from the weight of the air above. Pressure varies from day to day at the Earth. Figure 2-2 Mean pressure and temperature vs. altitude at 30oN, March. Atmospheric scientists partition the atmosphere vertically into domains separated by reversals of the temperature gradient, as shown in Figure 2-2.The troposphere extends from the surface to 8-18 km altitude depending on latitude and season. It is characterized by a decrease of temperature with altitude which can be.

In the 20th century, geoscientists discovered an increase in the velocity of p-waves, another type of body wave, at about 5,150 kilometers (3,200 miles) below the surface. The increase in velocity corresponded to a change from a liquid or molten medium to a solid. This proved the existence of a solid inner core The Spruce / Georgia Lloyd. Another common cause for home water pressure problems is a faulty pressure regulator or pressure-reducing valve. A pressure regulator is a control valve that reduces the input pressure in your plumbing system to a safe level that will not damage your pipes.Not all homes have them, but for those that do, a failing pressure regulator can cause a serious upward spike.

Why is the pressure in a liquid independent of the shape

Replace pump. Pump sucking air. Turn off machine (but not water supply) and release pressure by squeezing trigger gun. Obstructed nozzle, water inlet filter or gun/spray wand. Use needle to clear nozzle, fresh water to flush water inlet and vinegar to clear any deposits in gun/wand. 4 1. Comment on the variation of thrust with depth. 2. Comment on the relationship between the depth of the centre of pressure and the depth of immersion. For both (1) and (2) above, comment on what happens when the plane has become fully submerged. Comment on and explain any discrepancies between the experimental and theoretical results for the. Seismic velocities tend to gradually increase with depth in the mantle due to the increasing pressure, and therefore density, with depth. However, seismic waves recorded at distances corresponding to depths of around 100 km to 250 km arrive later than expected indicating a zone of low seismic wave velocity Step 2. Head pressure from hundreds of feet of depth behind a dam drives the mighty generators below. Divide the depth in inches by 27.71-inches/psi, or the depth in feet by 2.31-feet/psi which are the English unit conversion factors. The result is the water head pressure expressed in psi.

Beta blockers aren't recommended as a first treatment if you have only high blood pressure. Beta blockers aren't usually prescribed for high blood pressure unless other medications, such as diuretics, haven't worked effectively. Also, your doctor may prescribe a beta blocker as one of several medications to lower your blood pressure Fluctuating blood pressure can be caused by several issues. Stress. Emotional stress and anxiety can temporarily increase blood pressure. Over time, excess stress can take a toll on your. An important property of any gas is its pressure.We have some experience with gas pressure that we don't have with properties like viscosity and compressibility.Every day we hear the TV meteorologist give value of the barometric pressure of the atmosphere (29.8 inches of mercury, for example). And most of us have blown up a balloon or used a pump to inflate a bicycle tire or a basketball Experiment #1: Hydrostatic Pressure. 1. Introduction. Hydrostatic forces are the resultant force caused by the pressure loading of a liquid acting on submerged surfaces. Calculation of the hydrostatic force and the location of the center of pressure are fundamental subjects in fluid mechanics. The center of pressure is a point on the immersed.

In other words, if you consume a low-fiber diet, your body expels 25 grams of undigested organic and inorganic matter for every 100 grams of stools, and only eight of those grams come from food. The water in formed stools is retained by dead cells and intestinal bacteria, which are also single-cell organisms Selina solutions for Concise Physics Class 9 ICSE chapter 4 (Pressure in Fluids and Atmospheric Pressure) include all questions with solution and detail explanation. This will clear students doubts about any question and improve application skills while preparing for board exams. The detailed, step-by-step solutions will help you understand the concepts better and clear your confusions, if any Atmospheric pressure decreases as altitude increases. High altitudes contain less air molecules, resulting in lower air density, decreased temperatures and lower air pressure. High altitudes are typically found above sea level. Atmospheric pressure is measured as the weight of the air above a surface Factors Affecting Air Pressure: 1. Temperature: As the temperature increases, air expands because of which its density decreases which results in low pressure. On the other hand air shrinks due to low temperature because of which its density increases which creates high pressure. The relation between air pressure and temperature is defined with.

Fluid inclusions are tiny quantities of liquid, gas, or mixtures of the two, trapped within minerals. Their sizes range from 0.01 to 0.1 millimeters (0.0004 to 0.004 inches) in diameter. Inclusions may be observed within a given sample by cutting the mineral into very thin slices (30 to 35 microns [about 0.001 inch]) with a diamond saw and. The average air pressure at sea level (1013 mb or sometimes called one atmosphere of pressure) is caused by the weight of all the air above sea level. In the same way water pressure is caused by the weight of water above you. At a depth of 32 feet (9.75 meters) below a water surface, the water pressure is about one atmosphere A couple feet of water pressure isn't enough to do serious damage yet, but looking at deeper levels shows how pressure affects us a little more gradually. At a depth of around 100 feet, (remember, you'd have four times the normal pressure pushing down on you at this point), the spongy tissue of the lung begins to contract, which would leave. Barry A. Perlmutter, in Solid-Liquid Filtration, 2015 Cartridge Filter. Cartridge filters are available in various lengths and diameters as well as construction materials (woven, nonwoven, and membranes). The flow is outside-to-inside. Therefore, these filters require a strong core to be able to handle the increased pressure differential during operation Memory foam manufacturers claim this helps relieve pain and thereby promotes more restful sleep. And, though consumers often believe that very firm mattresses are best, more giving mattresses.

The increased pressure of each gas component at depth means that more of each gas will dissolve into the blood and body tissues, a physical effect predicted by Henry's Law. To review, Henry's law states that the amount of gas dissolving into any liquid or tissue with which it is in contact is proportional to the partial pressure of that gas. Trap seal is the maximum vertical depth of liquid that a trap will retain measured from the crown weir and the top of the dip of the trap. The most common of all plumbing traps is the p-trap. This is used with kitchen sinks, lavatories, and laundry sinks. Check out the diagram in Figure #1. Figure #1 Tubular P-Trap. Plumbing Codes Restriction

Pressure in Fluids and Atmospheric Pressure Selina Physics

Pressure is created by the number of collisions that occur between the molecules and the surface of container. If the temperature in the container is increased this will cause the molecules to move faster. As molecules move faster the number of collisions that will occur will increase. By increasing the number of collisions, this will increase the pressure in the container The liquid flows across the plate, while the gas bubbles up through holes in the plate (called a sieve tray). Each plate or tray has a short section of tubing cut through the plate. Figure 4. Sieve tray plate of a staged column. Each plate retains a liquid layer, the depth of which is controlled by the height of the weir Alpha-blockers are most commonly prescribed for men with mildly distressing symptoms. These can cause low blood pressure and dizziness when going from sitting to standing, so be careful when you start taking these medications. They include tamsulosin (Flomax), terazosin (Hytrin), doxazosin (Cardura), alfuzosin (Uroxatral), and silodosin (Rapaflo) globe vs. butterfly, etc. The important parameter in determining the PVC is - FL - Liquid Pressure Recovery Factor. As the name implies, the FL factor is a measure of the effective-ness of the reconversion of velocity pressure into static pressure from the main orifice of the throttling valve (@ vena contracta) to the valve's outlet
