Such as the renault number reynolds number flow rate flow the shock choking the involved joints in pipes fitting and the other by the values of these. C v flow calculator.
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.
Valve cv calculator for air. If this valve is connected to a 125 psig air line find the pressure loss through it when it is passing a flow of 243 scfm. Online calculator to quickly determine valve and orifice cv kvs values for air. Suppose a certain valve has a published cv factor of 3 75.
Instantaneous flow based on your stroke time and cylinder volume this is the amount of air your cylinder will consume if operated continuously for one minute. The kv value is a measure of the flow rate through a valve for a given medium and pressure drop. 93 cv and it will meet the flow conditions.
This is our valve c v calculator. The use of this flow coefficient c v calculator leads to a standard calculation to compare valve capacities. Gas relative density air 1.
The larger this value the higher the flow rate through the valve will be at a given pressure drop. Cv factor this is the minimum size valve required to control the cylinder at the set conditions. 55 18 8 2 93.
You will normally have to round this number up or down for an available valve cv. In deciding the size of the control valve that port size we need to calculate the cv value of the process calculated cv by calculating cv has educated more than 50 years which is involved in. Equations displayed for easy reference.
We have created a cv value and flow rate calculator so please utilize it. C v calculator for valve sizing. This calculator can be used to help select a valve with enough flow capacity for a given application.
Select a valve with at least a 2. Online calculator to quickly determine valve and orifice cv kvs values for air. To find necessary cv for a 55 scfm flow.
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. Usually the kv value is given in the product description or datasheet. Includes 53 different calculations.
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. 3 for p1 and p2 please use pressure close to the valve. If calculation is made using the pressure at the point away from the valve large errors may occur in the calculation results due to pressure loss etc.
