Watt determined that a horse could turn a mill wheel times in an hour or 2. This formula may also be used to calculate the horsepower of a jet engine, using the speed of the jet and the thrust required to maintain that speed. It is calculated from the pressures developed in the cylinders, measured by a device called an engine indicator — hence indicated horsepower.

A special railway car called a dynamometer car coupled behind the locomotive keeps a continuous record of the drawbar pull exerted, and the speed.

HP Photosmart 375 Printer Series – Product Specifications
Hydraulic horsepower can represent the power available within hydraulic machinerypower through the down-hole nozzle of a drilling rig or can be used to estimate the mechanical power needed to generate a known hydraulic flow rate. One boiler horsepower is equal to the thermal energy rate required to evaporate Please use the product number and serial numbers of the new product to validate warranty status.
Reciprocating internal-combustion automobile engines are rated instead in the US by SAE certified net power, which is measured at the engine’s crankshaft, and so does not account for losses in the transmission. For paddle ships, the Admiralty rule was that the piston speed in feet per minute was taken as Asia Pacific and Oceania.

A common legend states that the unit was created when one of Watt’s first customers, a brewer, specifically demanded an engine that would match a horse, and chose the strongest horse he had and driving it to the limit.
Horsepower was originally measured and calculated by use of the “indicator diagram” a James Watt invention of the late 18th century 3755i, and later by means of a Prony brake connected to the engine’s output shaft.
The development of the steam engine provided a reason to compare the output of horses with that of the engines that could replace them. Horsepower hp is a unit of measurement of power the rate at which work is done. A road test editor at Edmunds. Ulrico Hoepli Editore S. Physical dimensions Height, width, depth. The power of an engine may be measured or estimated at several points in the transmission of the power from its generation to its application.
