The relationship between Horsepower (HP), Torque, and RPM can be rearranged to calculate RPM using the following formulas:
\( RPM = \frac{\text{HP} \times 63025}{\text{Torque (lb.in)}} \)
\( RPM = \frac{\text{HP} \times 5252}{\text{Torque (lb.ft)}} \)
\( RPM = \frac{\text{HP} \times 712.4}{\text{Torque (Nm)}} \)
- \( \text{HP} \): Horsepower.
- \( \text{Torque} \): Rotational force (in lb.in, lb.ft, or Nm).
- \( RPM \): Revolutions per Minute (to be calculated).
If the horsepower is 50 HP and the torque is 100 lb.ft:
\( RPM = \frac{50 \times 5252}{100} = 2626 \, \text{RPM} \)
This calculator helps determine the RPM of a rotating system based on horsepower (HP) and torque, useful in automotive and mechanical engineering applications.
Yes, the calculator supports torque in lb.in, lb.ft, and Nm, using the appropriate formula for each unit.
