The flow coefficient of a gadget is a relative measure of its proficiency at permitting liquid flow flow expressed by weight. The valve flow coefficient c v is a convenient way to represent flow capacity of a valve across a range of fluids and process parameters the c v calculator will calculate either c v or flow using the supplied additional parameters of fluid inlet and outlet.
Online calculator to quickly determine valve and orifice cv kvs values for water.
Cv flow calculator water. Flow for a given cv is typically calculated from the following formula. The use of this flow coefficient c v calculator leads to a standard calculation to compare valve capacities. Flow coefficient calculator.
C v 25 gpm 1 1 psi 1 2 25 flow coefficient c v for saturated steam since steam and gases are compressible fluids the formula must be altered to accommodate changes in. C v flow calculator. Includes 53 different calculations.
The flow coefficient cv of water is the volume of water at 60 f that will flow per minute through a valve with a pressure drop of 1 psi across the valve. Equations displayed for easy reference. The flow coefficient of the gadget is a relative measure of its efficiency in allowing liquid flow.
M3 h for a pressure drop of 1 psi 1 bar across a flow passage flow coefficient. Flow coefficient of water calculator. It allows you to calculate the flow or c v flow coefficient to make the relationship visible between the pressure drop the difference in pressure between two points in a network transporting a liquid or gas and the flow rate.
Cv value flow rate calculator what is cv value. They express coefficient cv kv as the flow rate of water in g p m. Example flow coefficient liquid.
You can use the calculator to calculate maximum flow rate through control valve for given pressure drop and known flow coefficient of control valve cv. Obtain the flow coefficient cv of water based on the water flow specific gravity and pressure drop. The valve flow coefficient c v is a convenient way to represent flow capacity of a valve across a range of fluids and process parameters the c v calculator will calculate either c v or flow using the supplied additional parameters of fluid inlet.
This calculator can be used to help select a valve with enough flow capacity for a given application. Cv calculator for water. C v calculator for valve sizing.
The valve flow coefficient according to the jis standard represents the flow capacity in us gallons minute of 60 f pure water when it is flowing through the valve with a pressure difference of 1 psi at the specified travel operation range. The flow coefficient for a control valve which in full open position passes 25 gallons per minute of water with a one pound per square inch pressure drop can be calculated as. This is our valve c v calculator.
