WebOct 10, 2024 · E = 0.5*I*ω 2. = 0.5*0.714*335 2. = 40,000 Joules. If it takes 10mins = 600 seconds to stop then a very rough estimate of the power required to overcome friction and other losses in the flywheel is. 40,000/600 = 67W. In other words it takes <100W to keep the flywheel turning at a constant speed. WebSep 16, 2015 · ω = Mean angular speed during the cycle in rad / s = ω1+ω2 / 2. Cs = Coefficient of fluctuation of speed = N1-N2/N or ω1-ω2 / ω. We know that mean kinetic energy of the flywheel, E = 1/2 × I ω^2 = 1/2 ×m k^2 ω^2 (in N-m or joules) As the speed of the flywheel changes from ω1 to ω2, the maximum fluctuation of energy,
