How to calculate how much power required to turn a flywheel? Suppose I have a flywheel of 24 inch diameter, width 5 inches,50kg. How do I calculate the required power (HP) to turn this or any other with different values?
Ring's KE(joules): 101932.01Then find the kinetic energy of the rotating flywheel at the required rotation rate and divide by the time.
You can approximate the flywheel with a cylinder when looking up the moment of inertia.
Ring's KE(joules): 101932.01
Time is 10 second
Is it the power required to rotate that flywheel? Please elaborate, I really don't know how to calculate? I have attached flywheel's energy calculations.
So in this case, power required to rotate 50 kg, 0.3048m radius flywheel @ 2000 rpm for 10 sec isYou don't need the torque. Once you have the kinetic energy, the average power will be that energy divided by the time.
No. This is not correct.So in this case, power required to rotate 50 kg, 0.3048m radius flywheel @ 2000 rpm for 10 sec is
101932/10=10193.2 watts. Is this correct?
