Enter the valve flow coefficient (CV) and the pressure differential (PSI) into the GPM from CV Calculator. The calculator will evaluate the GPM from CV.

## GPM from CV Formula

The following two example problems outline the steps and information needed to calculate the GPM from CV.

GPM = CV * SQRT (P)

Variables:

• GPM is the GPM from CV (gallons per minute)
• CV is the valve flow coefficient (CV)
• P is the pressure differential (PSI)

To calculate GPM from CV, multiply the valve coefficient by the square root of the pressure differential.

## How to Calculate GPM from CV?

The following steps outline how to calculate the GPM from CV.

1. First, determine the valve flow coefficient (CV).
2. Next, determine the pressure differential (PSI).
3. Next, gather the formula from above = GPM = CV * SQRT (P).
4. Finally, calculate the GPM from CV.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

valve flow coefficient (CV) = 2.5

pressure differential (PSI) = 30

GPM = CV * SQRT (P) = ?
