Precisely 1/2 horsepower.

Watt defined one horsepower as "the amount of work required from a horse to pull 150 pounds out of a hole that was 220 feet deep".

You're welcome.

thus over the course of a day Watt was fairly accurate in terms of 1hp being the amount of work a horse could sustain. But for short periods at full tilt a horse can muster about 15hp (and similarly a human is about 1hp peak). But for the purposes of comparing his new fangled steam engines as horse replacements for continual work over the course of a day, Watt’s definition was pretty accurate.

You’re more than welcome.

Ok. Precisely half a horse power.

You're both welcome.

That's change in potential energy (mgh).

Power is a measure of the rate at which work is done (or similarly, at which energy is transferred). Did Watt really ignore time?

Am I banned now?

You've been banned for months.

Have a nice day.

Change in PE = Final PE - Initial PE.

Use it or lose it

Nope - Watt accounted for time. Wiki confirms…

Watt determined that 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 force of 180 pounds-force (800 N).

I remember the concept and the horse=15hp peak from my Mech.Eng degree…but that was just short of 50 years ago so have to rely on Wiki for the finer details.

My question was rhetorical.

I graduated with a Mech Eng degree in 1976. So many moons ago like you.

I’m a youngster then - I graduated in 1979.

Use it or lose it

so if you lose it does that make it No power to = NPE - and therefore as it's so full of hot-air and BS it's actually infinite power?

I think you're correct and guess what?
