Remind me to take attendance shirt
Watt later determined that Remind me to take attendance shirt a horse could turn a mill wheel 144 times in an hour (or 2.4 times a minute). The wheel was 12 feet (3.7 m) in radius; therefore, the horse travelled 2.4 × 2π × 12 feet in one minute. Watt judged that the horse could pull with a of 180 pounds-force (800 N). So Watt defined and calculated the horsepower as 32,572 ft⋅lbf/min, which was rounded to an even 33,000 ft⋅lbf/min.
Unfortunately the concepts of physics were Remind me to take attendance shirt somewhat unclear at the time, and while Watt insisted horsepower ought to be the unit of power, it really would have been the unit of effort (force). On more handier units, one hp equals 550 ft⋅lbf/s.
