Horsepower (hp) is a unit of ... This formula may also be used to calculate the power of a jet engine, using the speed of the jet and the thrust required to maintain ...
One metric horsepower is needed to lift 75 kilograms by 1 metre in 1 second. Power in mechanical systems is the combination of forces and movement. In particular, power is the product of a force on an object and the object's velocity, or the product of a torque on a shaft and the shaft's angular velocity.
The tax horsepower or taxable horsepower was an early system by which taxation rates for ... Under the RAC's formula the Model T was a 22 'tax horsepower' car, making ...
Engine power is the power that an engine can put out. It can be expressed in power units, most commonly kilowatt, pferdestärke (metric horsepower), or horsepower.In terms of internal combustion engines, the engine power usually describes the rated power, which is a power output that the engine can maintain over a long period of time according to a certain testing method, for example ISO 1585.
The Firebird Esprit and the Firebird Formula came standard with the 255 hp (190 kW), 350 cu in (5.7 L). The Esprit could be upgraded to a two-barrel carbureted 400 cu in (6.6 L), 265 hp (198 kW), while the Formula could be optioned to receive the L78 4 barrel 400 that produced 330 hp (246 kW) or the L74 Ram Air III 400 345 hp (257 kW).
In the following formulas, ... The horsepower form of the equation is then derived by applying the conversion factor 33,000 ft⋅lbf/min per horsepower:
A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines.
The term "brake horsepower" is one measurement of power derived from this method of measuring torque. (Power is calculated by multiplying torque by rotational speed .) [ 1 ] Essentially the measurement is made by wrapping a cord or belt around the output shaft of the engine and measuring the force transferred to the belt through friction .
