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.

- First, determine the valve flow coefficient (CV).
- Next, determine the pressure differential (PSI).
- Next, gather the formula from above = GPM = CV * SQRT (P).
- Finally, calculate the GPM from CV.
- 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)** **= ?
