Torque From Power Formula
The following formula is used to calculate the Torque From Power.
T = P * 60 / (2*pi*RPM)
- Where T is the Torque From Power (N-m)
- p is the total power (kW)
- RPM is the total rotational speed (RPM)
To calculate torque from power, multiply the power by 60, then divide by the result of 2 times pi times the RPM.
How to Calculate Torque From Power?
The following two example problems outline how to calculate the Torque From Power.
Example Problem #1:
- First, determine the total power (kW). In this example, the total power (kW) is measured to be 500.
- Next, determine the total rotational speed (RPM). For this problem, the total rotational speed (RPM) is calculated to be 30.
- Finally, calculate the Torque From Power using the formula above:
T = P * 60 / (2*pi*RPM)
Inserting the values from above and solving the equation with the imputed values gives:
T = 500 * 60 / (2*3.14159*30) = 159.155 N-m
Example Problem #2:
Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:
total power (kW) = 780
total rotational speed (RPM) = 210
Entering these values into the formula or calculator above gives us::
T = 780 * 60 / (2*3.14159*210) = 35.468 (N-m)
