Horsepower vs. Torque And because one of Watt's horses says that's the way it ought to be, one horsepower is equal to the amount of power it takes to perform 33,000 ft-lb of work in a single minute. In other words, one horsepower is equal to the amount of energy required to lift 550 pounds one foot in one second.

"Question Does ""horsepower"" mean anything?" Horsepower is a measurement of an engine’s power. It is measured on a dynamometer that test how much power and strength (torque) the engine has before the dynamometer can stop or break it. Hence the term brake – Horsepower and torque which measures the twisting power of an engine.

- horse power = kilowatts. 10 = 7.355. Metric horsepower is exactly defined as 0.73549875 kW (kilowatts), that is roughly 98.6% of US mechanical horsepower. Metric horse power is widely used in auto industry to indicate power of car engines in Europe and Asia. French, Japanese, Korean, German, Swedish, Italian and other automobile companies use this unit.

Horsepower For the nominal horsepower to equal the actual power it would be necessary for the mean steam pressure in the cylinder during the stroke to be 48 kPa (7 psi) and for the piston speed to be of the order of 54–75 m/min. The French Navy used the same definition of nominal horse power as Britain.

Pumps, Fans and Turbines - Horsepower British Horse Power in pumps, fans and turbines - and how to convert to other commonly used units. Horsepower. Horsepower is the imperial (British) unit of power. Note that Power is Work per unit time and work is Force through distance. In gravity systems Force is Weight - mass multiplied with gravity. The total horsepower developed by water falling from a given height is the product of the mass flow rate in pounds per minute times the falling height in feet divided by 33000.

Horsepower: Gross vs. Real-World Wheel-driven horsepower, by comparison, is a measurement taken at the driven wheels of a vehicle on what's called a dynamometer. This is done by placing the vehicle's driven wheels on a large roller and accelerating the wheels up to redline in first or second gear.

"Where dose the term ""horsepower"" come from?" Horsepower is a measurement of an engine's rate of doing work. The term horsepower was originally coined by James Watt, an English engineer/inventor, in the mid-1700s. Watt focused a great deal of his energy on perfecting the steam engine used in coal mining and for other tasks of the day.

Horsepower The horsepower used for electrical machines is defined as exactly 746 W. In the US, nameplates on electrical motors show their power output in hp, not their power input. Outside the United States watts or kilowatts are generally used for electric motor ratings and in such usage it is the output power that is stated.

Difference Between BHP and PS BHP vs PS. There are a number of ways to measure the power that can be generated by a mechanical device like a car. The most popular is brake horsepower or BHP, which is a method of measurement for vehicles without the encumbrance added by connecting devices like the gearbox and transmission system. In comparison, PS is a unit of power in German. Although PS is very popular in Germany and in Europe, it is rarely seen anywhere else. There are a number of ways to get the brake horsepower of an engine using a number of devices like the De Prony brake.

What is the difference between torque and horsepower in automobiles? Horsepower is defined as the amount of energy required to lift 550 pounds, one foot, in one second. From this definition you can see that the components of horsepower are force, distance and time. Distance and time are self-explanatory but force, specifically a twisting force, is what torque is all about.

- In the past, before the widespread adoption of SI units, the work that engines were capable of doing was compared with the work that horses could do – hence the term ‘horsepower’. Various people came up with various equivalencies, but the modern agreed definition is that 1 horsepower is 746 joules per second or 746 watts. A metric horsepower (symbol often PS from the German abbreviation), approximately equal to 735.5 watts. Strength political horsepower.
