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
