an engine with a brake horse power of 20 bhp would have a rated horsepower of?

Question

A. 24 HP
B. 18 HP
C. 16 HP
D. 10 HP

Answer 1

What?

BHP refers to an old way to measure horsepower (before engine dynos were the norm) called a prony brake.

I'm not sure where you got the data for your answers, but there's no correct answer here.

Answer 2

BHP is and most of the time has been Mis explained as Brake HorsePower... Which is wrong...

bhp is BASE Horse Power..... b = base, aka, measured at the
flywheel.

In the late 60's it became the term as you know it and was used til 1972

Brake horsepower (bhp)
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 auxiliaries. 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 use of a band brake to measure torque during the test (which is multiplied by the engine speed in revs/sec and the circumference of the band to give the power).


So you question is incomplete or you Have E,
which is 20 HP or enter which engine VS drive train...
Example a 20bhp VW engine might have 16hp
at the wheels but a Tractor with 20bhp would be near 10hp...

Since 1972 hp (SAE)
In the United States the term "bhp" fell into disuse after the American Society of Automotive Engineers (SAE) recommended manufacturers use hp (SAE) to indicate the net power of the engine, given that particular car's complete engine installation. It measures engine power at the flywheel, not counting drivetrain losses.
SAE gross ratings were applied liberally
