The point at which the horsepower measurement is taken. A 100hp outboard engine may only deliver 87 horsepower to the propeller due to losses in the transmission and bearings. The engine horsepower is 100, but the shaft horsepower rating is 87 horsepower.

What is the difference between Shaft horsepower and Brake horsepower?

Shaft horsepower is the power output from an engine after it is put through the gear train and other components that result in a loss of power. It is usually used in respect to aeroplanes and ships though it can be used as the power output from a cars gearbox. Brake horsepower is the power an engine puts out at the crank and is not subject to losses. It is always higher than the true horsepower. The true horsepower or rear wheel horsepower is the power that is actually driving a vehicle foreward and is probably the most important for comparing motor vehicles. Horsepower itself is the imperial unit for power, like the metric systems Watt. 1 hp = 0.75kW

What does bhp brake horsepower mean?

Brake horse power is the power output of the drive shaft on an engine without the power loss caused by the gears, transmission, friction, etc. The actual useful horsepower delivered to the propellor or wheel is called the shaft horsepower. Its also called effective ,true, wheel horsepower as well as other terms. The term horsepower is is not a good measurement of power as there asre too many different systems of measuring horsepower. The current trend is to use kilowatts or megawatts.

Is the brake power the output power of an engine?

No, "Horsepower" was originally defined to compare the output of steam engines with the power of draft horses. "Brake horsepower" (BHP) is the amount of work generated by a motor without taking into consideration any of the various auxiliary components that may slow down the actual speed of the motor. Sometimes referred to as pure horsepower, brake horsepower is measured within the engine's output shaft.

IN reference to autos What is the difference between brake horse power and barrel horse power?

Brake horsepower (bhp) is the measure of an engine's horsepower without the loss in power caused by the gearbox, generator, differential, water pump, and other auxiliary components. Thus the prefix "brake" refers to where the power is measured: at the engine's output shaft, as on an engine dynamometer. The actual horsepower delivered to the driving wheels is less. An engine would have to be retested to obtain a rating in another system. The term "brake" refers to the original use of a band brake to measure torque during the test (which is multiplied by the engine RPM and a scaling constant to give horsepower).
