Watt coined the term “horsepower,” which he used to convey the power of his engines; Watt calculated how many horses it would take to do the work of each engine. One horsepower equals 33,000 foot-pounds of work per minute; it is the power required to lift a total of 33,000 pounds...
the consumption of coal on the grate will become comparatively very small. Even with a small two-horsepower apparatus, in which no very great precautions were taken to retain the heat, measurements showed that only one-third of a pound of coal per electrical horsepower hour was burned on a ...
