WebFeb 7, 2013 · The units are different, for starters. "Brake horsepower" can be likened to the maximum thermal power that can be dissipated within a friction brake mechanism that is opposing the rotation of a shaft. It is the product of the torque applied and the angular velocity of the shaft, expressed in consistent units. WebJan 20, 2012 · The overall efficiency of a centrifugal pump is simply the ratio of the water (output) power to the shaft (input) power and is illustrated by the equation below: Ef = PW / PS. Where: E f = efficiency. P w = the water power. P s = the shaft power. In the U.S., Ps is the power provided to the pump shaft in brake horsepower (BHP) and Pw is: Horsepower is the imperial (British) unit of power. A horsepower is the ability to do work at the rate of 1. 33000 ft.lb per minor 2. 550 ft.lb per second Note that Power is "Work per unit time" and work is "Force through distance". In gravity systems the Force is Weight- mass multiplied with gravity. In the SI system the unit … See more Required horsepower (hp) to pump 1 cubic foot of water per minute (ft3/min) with efficiency 85%- is indicated in the diagram below: 1. 1 hp … See more Horsepower can be converted to other common unitsas: 1. 1 hp (English horse power) = 745.7 W = 0.746 kW = 550 ft.lb/s = 2545 Btu/h = 33000 ft.lb/m = 1.0139 metric horse power Transforming horsepower to kW: … See more The brake horsepower is the amount of real horsepower going to the pump, not the horsepower used by the motor.
