What a messy measurement that is these days... https://en.wikipedia.org/wiki/Horsepower Anyway, Power = force x distance / time 1 cubic foot of water at STP weighs 62.42796 pounds. That's the force. So, Power = 62.42796 x 100 / 1 Power = 6243 ft.lbf/s (rounded, no more silly decimal places) Since 1 mechanical horsepower is defined as 550 ft.lbf/s, Power = 6243 / 550 = 11.35 mechanical horsepower. Do I get a prize? Please, consider using watts instead ;-)
