A unit for estimating the rate at which an agent works. It works with one horse-power when it performs 33,000 foot-pounds of work per minute. The Nominal H. of a steam-engine is estimated by its dimensions. The Actual or Indicated H. is that of the steam on the piston in the actual working of the engine, and is ascertained by the steam-indicator.
