Centrifugal Pump Efficiency Calculation
Centrifugal pump efficiency is the ratio of Hydraulic power delivered by the pump to the brake horsepower supplied to the pump. Hydraulic Power (Power Output from Pump): Centrifugal Pump consumes energy to develop the discharge pressure and to deliver flow. Therefore Hydraulic Horsepower of the Pump depends on these two parameters. Power Output from Pump = (P2 – P1) * … [Read more...]
