I'm using a 3 phase 5HP motor pump n want to use capacitor. Which capacitor should I use and how to connect it to all the three phases? Please do needful

no, i was asking that time divided the KE is what? is it the total time or something else? i got the answer. thanks A.T. :-)

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?Power = KE/time; What does the time means? Is it the total time for which we r rotating the flywheel? What will be the value if I want to rotate that...

i got some values, please check values @ 2000rpm, 50 kg, 0.3048m radius rpm to rad/sec = rpm*2*pi/60; i.e. 209.33 rad/sec ; I = 0.5 m r^2 = 0.5*50*0.3048*0.3048 = 2.3225; E = 0.5 I ω ^2 = 0.5*2.3225*209.33*209.33 = 50884.8705 Joules; <== torque = mass moment of inertia * rotational...

Ring's KE(joules): 101932.01 Time is 10 second 101932/10=10193.2 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.

In 10-12 seconds. :-)

To accelerate from rest to 2000rpm

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?
