Equivalent Power
Equivalent Power
an arbitrary power rating used, for example, in the analysis of statistical data to compare engines, machines, and other equipment of different powers in order to depict them as a given number of machines having the same power rating. Thus, data on a tractor fleet in the USSR are sometimes converted into arbitrary units of 15-hp tractors (1 hp = 0.736 kilowatt), that is, 15 hp at the drawbar is taken to be the equivalent power. A tractor that develops 75 hp at the drawbar, then, is equivalent to five tractors of 15 hp each.
