Pump Efficiency Calculator
Pump Efficiency refers to the ratio of energy that is converted into useful work to the energy applied to the pump shaft or the energy difference in the water.
Table of Contents:
Formula
Pump Efficiency :
n= WHP / BHP
Water Horsepowe :
WHP = n*BHP
Brake Horsepower :
BHP = WHP /n
Where,
n = Pump Efficiency,
WHP = Water Horsepower,
BHP = Brake Horsepower.
Pump efficiency is termed as the ratio of the power or energy imparted on the fluid by the pump in relation to the power supplied to drive the pump.
Example:
Calculate the Pump efficiency for the given details of horsepower.
Water Horsepower (WHP) = 25 HP
Brake Horsepower (BHP) = 20 HP
Solution:
Apply Formula:
n= WHP / BHP
n = 25/20
n = 1.25
Pump Efficiency (n) = 1.25
