Solving For Brake Horsepower
Brake Horsepower
Note: Equation for water at 68 Fahrenheit. Usually, temperature correction for water is negligible.

Inputs:

discharge or flow rate (Q)
total head (H)
pump efficiency (n)


Conversions:

discharge or flow rate (Q)
= 0
= 0
gallon/minute
total head (H)
= 0
= 0
foot
pump efficiency (n)
= 0
= 0

Solution:

brake horsepower (WHP)
= NOT CALCULATED
