## 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 (%)

## Brake Horsepower Definition

Brake horsepower is the total amount of horsepower or energy required to overcome the force of breaking in a centrifugal pump.

## Brake Horsepower Example

How to calculate brake horsepower?

**First, determine the flow rate.**Measure the flow rate of the fluid moved by the pump.
