Formula for calculations of Break horsepower is
BHP = (Torque × RPM )/5252,where torque is lb -ft and n = revolution per min.
How is BHP measured?
Brake horsepower (bhp) is the power measured using a brake type (load) dynamometer at a specified location, such as the crankshaft, output shaft of the transmission, rear axle or rear wheels. ... During testing, the output torque and rotational speed are measured to determine the brake horsepower.
How is brake power calculated?
The power developed by an engine at the output shaft is called brake power and is given by Power = NT/60,000 in kW where T= torque in Nm = WR W = 9.81 * Net mass applied in kg.
