Power (physics) In physics, power is the rate of doing work. It is the amount of energy consumed per unit time. Having no direction, it is a scalar quantity. In the SI system, the unit of power is the joule per second (J/s), known as the watt in honour of James Watt, the eighteenth-century developer of the steam engine.

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.

Torque vs horsepower Horsepower is a combination of torque and RPM. For pulling a lot of weight, lots of torque is nice because it gives you adequate horsepower at an reasonable RPM. 450 lb. ft. of torque at 2,500 RPM will give you about 215 HP. 215 HP will do a lot! The 30,000 lb. school bus I drive only has 240 HP and it gets around.

What does horse-power mean? Rating Newest Oldest. Best Answer: In physics terms, horsepower is used to measure the amount of work done. Work done is the mathematical expression of force x distance x time and is typically in ft/lbs/mins (Imperial) or Newton/Meters/mins (Metric). Horsepower was first coined by James Watt to measure the output of his new steam engines.

Horsepower In certain situations it is necessary to distinguish between the various definitions of horsepower and thus a suffix is added: hp(I) for mechanical (or imperial) horsepower, hp(M) for metric horsepower, hp(S) for boiler (or steam) horsepower and hp(E) for electrical horsepower. Hydraulic horsepower is equivalent to mechanical horsepower. [citation needed] The formula given above is for conversion to mechanical horsepower from the factors acting on a hydraulic system. Mechanical horsepower

"Where dose the term ""horsepower"" come from?" Best Answer: The term horsepower was coined by the engineer James Watt (1736 to 1819) in 1782 while working in the performance of steam engines. This occurred while using a mine pony to lift coal out of a coal mine. He conceived the idea of defining the power exerted by these animals to accomplish this work.

Net Horsepower vs. Gross: Definition and Ratings Guide The net horsepower is actually the measured output of the car with the alternator, power steering, AC and other peripherals included as well as smog control. This is measured at the engine crankshaft. This was the standard rating used in the auto industry until 2005.

What is the meaning of torque and power in a car in layman terms? If you say a car has a particular torque at 3000 rpm and power at 4500rpm, what does it mean? Horsepower is a unit of power which is the amount of work (W) which can be performed in a unit of time (t). Torque (tau) is a measure of force (F) applied across a moment arm (r). You can think of horsepower as literally the amount of power that a horse could perform. You can think of torque as the amount of twisting force on a crankshaft.

What is horsepower? Plain English guide to HP, BHP, kW, PS and CV Brake-horsepower is, in car terms, effectively the same as horsepower and simply indicates that an engine’s energy loss due to friction has been taken into account – though, because horsepower usually includes this anyway, they are effectively the same.

Horsepower Calculator Watt. Horsepower is not recognized in the International System of Units (SI); SI uses a measurement of power (a rate at which energy is generated or used) called a watt, which is named after James Watt. A watt is defined as one joule per second and is generally used to quantify a rate of energy transfer for smaller rates of power consumption such as lightbulb or smartphone charging.

The truth about horsepower in blenders and food processors What is peak horsepower and why does it matter? Peak horsepower is the amount of power generated when the motor meets resistance, such as the instant the motor starts spinning. This initial boost in torque makes the start of the blending process easier. Soon thereafter (a split-second, at best), the power of the motor drops to the running horsepower.
