Rotary horsepower calculator
Calculation of rotational horsepower, torque, speed
Select the appropriate unit and enter a value and click on "Calculate". The result will be displayed.
\(rotating horsepower=\frac {torque×speed}{5252}\)
\ (torque = \frac {5252 × horsepower} {speed} \)
\(speed=\frac {5252×horse}{torque}\)
Known data: torque; speed, what is the rotational horsepower?
Input data: Torque: 1000 lb-ft; Speed: 10 rpm
Output: Rotating horsepower: 0.019040 hp
