Flow rate calculation cv
Did you know?
WebThe Cv value for fluids can be found using the following formula: Where: Cv = Valve flow coefficient Q = Volumetric flow rate (SCFH – Standard Cubic Feet/Hour) P1 = Inlet …
WebFig. 1: Basic calculation for CV, where Q is the rate of flow (gallons per minute), SG is the specific gravity of the fluid, and P is the pressure drop across the valve (psi). Because air is compressible, CV must have additional factors built into the equations to compensate for that compressibility. For pneumatic applications, CV should be ... WebFill Flow velocity or Volumetric flow rate together with Column diameter and hit the "Convert" button to calculate the empty field. Hit reset button to clear the fields. The …
WebFlow is proportional to the value of Cv. For example, a Cv of 150 would then equate to 150 gpm of water at 60' F with a differential pressure of one psi. The formula below allows for … WebThe flow factor, or flow coefficient of a valve shows the relationship between the pressure drop and the flow rate. K v is the flow coefficient in metric units, and can be calculated with the following equation: where . K V: Flow factor (m 3 ·h-1 ·bar-0.5) Q: Flow rate (m 3 /h) SG: Specific Gravity of the liquid (dimensionless). For water SG=1
WebA K v value is defined as the rate of flow of water in m 3 /hr and 4°C at a pressure drop of 1 bar across the equipment. K v relates to pressure drop and flow rate via the following expression: \displaystyle K_v = Q \sqrt { \frac {SG} { \Delta P}} K v = Q ΔP SG. Where Q is in m 3 /hr and ΔP is in bar. Thus for a given K v, ρ and Q the ...
