Enter the flow rate, dynamic head, specific gravity and efficiency into the calculator to determine the brake horsepower.

## Brake Horsepower Formula

The following formula is used to calculate a brake horsepower of a centrifugal pump.

BHP = Q * DH * SG / 3960 * E

- Where BHP is the brake horsepower
- Q is the flow rate (gallons/min)
- DH is the total dynamic head (ft)
- SG is the specific gravity of the fluid
- E is the efficiency (%)
