BHP = Flow(GPM) X TDH(FT) x SG /3960xEFFICIENCY(%)Example: BHP = (100 GPM) x (95 Ft) x (1.0) / 3960 x .6BHP = 4.0
Brake horsepower is the hvac motor horsepower before the motor hp is dropped due to a load. Indicated, gross and SAE are other ways to rate horsepower.
The brake horsepower (BHP) of the average 50cc scooter engine is about 3 to 4. In most states, any engine with more than 5 horsepower must be registered as a motorcycle.

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
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.
The brake horsepower varies as a cube of the impeller diameter.
Brake Horsepower doesn't "do" anything, it's a rating of the engine's power before any parasitic loads (alternator, transmission, water pump, etc.) are added.
"they are basically equal"- Previous Answer They are not even close to equal. You can't calculate brake horsepower from wheel horsepower unless you know the exact losses through the drivetrain of the vehicle in question. The actual percent lost through any given drivetrain can vary dramatically. In order to know the losses you would need to measure the % difference between the brake horsepower and the wheel horsepower. Then you would already know the brake horsepower, and any calculations would be unnecessary. FYI- Brake horsepower is a rating of the engine output before the drivetrain/water pump/alternator/other attachments. It will be a higher number than wheel horsepower. It is measured by a brake dynomometer at the crankshaft of an engine. Wheel horsepower is generally 15-20% less (sometimes more than 20% less) than brake horsepower depending on whether the vehicle is FWD or RWD, or manual or automatic transmission. Usually the least losses will be in a FWD, manual transmission, and the most losses will be in a RWD, auto transmission. Auto manufacturers rate their engines in brake horsepower, as it allows them to advertise higher horsepower numbers than what is actually going to the ground.
yes of course.
what formula is used for calculate flow rate of pump vs kw
According to Triumph, it is 54 bhp (brake horsepower) @ 6,750 rpm. According to Encyclopedia Britannica, horsepower at the output shaft of an engine, turbine, or motor is termed brake horsepower or shaft horsepower.
Brake horsepower is the hvac motor horsepower before the motor hp is dropped due to a load. Indicated, gross and SAE are other ways to rate horsepower.
Horsepower and Brake horsepower are really the same thing as far as mathematical calculation. The difference is how it is measured. Brake horsepower is usually a measure of an engine's horsepower at the shaft WITHOUT anything attached to the engine that would normally be required like the water pump, alternator, power-steering pump, airconditioner, etc. Brake horsepower is usually a theoretical calculation or a measurement made only in a lab under controlled conditions since an engine cannot run without most of the things that it would be required to remove. In the lab/shop they would conect the engine to the dynomometer and then supply coolent, oil pressure, electricity, etc through external means.
The difference between brake horsepower and horsepower or wheel horsepower, they are the same thing, is that brake horse power is the power produced by the crank. The wheel horsepower is the amount of power delivered to the wheels. Brake horsepower refers to the method used to test the engine. A brake is attached to the engine and used to maintain the engine at a constant RPM at full throttle. The delivered power output is then a simple calculation of RPM times torque. Horse power is based on the average amount of work that a horse could do in a day. It is taken to be 746watts. well you guessed it engine output is also specified in kilowatts so divide by 746 and you have horsepower. As stated above it is all the same thing. There is a difference between advertised horsepower and brake horsepower. Advertised horsepower is what a manufacturer will rate its engine/automobile/machine to produce. Brake horsepower is the actual measured horsepower, for example, of a motor on an engine dynamometer.
