Enter the pump pressure (PSIG) and the flow rate (GPM) into the calculator to determine the Pump Power.

## Pump Power Formula

The following formula is used to calculate the Pump Power.

**Pp = P * Q / 1714**

- Where Pp is the Pump Power (horsepower)
- P is the pump pressure (PSIG)
- Q is the flow rate (GPM)

## How to Calculate Pump Power?

The following two example problems outline how to calculate the Pump Power.

**Example Problem #1:**

- First, determine the pump pressure (PSIG). In this example, the pump pressure (PSIG) is measured to be 21.
- Next, determine the flow rate (GPM). For this problem, the flow rate (GPM) is calculated to be 500.
- Finally, calculate the Pump Power using the formula above:

Pp = P * Q / 1714

Inserting the values from above and solving the equation with the imputed values gives:

Pp = 21 * 500 / 1714 = 6.12 (horsepower)

**Example Problem #2: **

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

pump pressure (PSIG) = 100

flow rate (GPM) = 40

Entering these values into the formula or calculator above gives us::

Pp = 100 * 40 / 1714 = 2.33(horsepower)
