What is the simple formula for calculating horsepower? I have a question using pounds, feet & seconds. thanks!

Question

Is the simple formula for horsepower (pounds)(feet) divide seconds? I can't seem to find it. Thank you.

Answer 1

You do have your answers.

But here is the explanation.

If you move 1 Pound thru 1 foot then you have done a work equal to foot pound.

Now if you do this in one sec second then it is foot pound per sec. This is the power used to do this work.

So if you move 550 pounds thru 1 foot in one sec. then it is 550 foot pound/sec

This is 1 horse power. By definition (people in olden days were used to horses and they understood how much a horse can do, so they needed comparison to buy new machinery so engineers estimated this work capacity of and average horse and came up with this figure as a standard for the measurements).

1 HP = 550 foot-pounds per second.

Answer 2

Horsepower Formula Physics

Answer 3

The conversion is:

1 HP = 550 foot-pounds per second.

You could Google "conversion" "horsepower" and pull up the Google conversion page(s)

.

Answer 4

You have all of the units that you need. One horse poweris equal to 550 foot pounds per second. By the way, if you are also working withheat, 1 BTU equals 777.5 foot pounds.

Answer 5

One formula is HP=torque*RPM/5252
torque multiplied by the rpm divided by the number 5252
