GPH to HP Calculator

Calculate Horsepower (HP)





Formula

The formula to calculate the Horsepower (HP) is:

\[ HP = \frac{GPH \cdot P}{1714 \cdot E} \]

Where:

Definitions

Example

Let's say the gallons per hour (GPH) is 500, the pressure (P) is 100 psi, and the pump efficiency (E) is 0.85. Using the formula:

\[ HP = \frac{500 \times 100}{1714 \times 0.85} \]

We get:

\[ HP \approx 34.29 \, \text{HP} \]

So, the horsepower required is approximately 34.29 HP.
