WebPower required : P = T ω. Where: J = Polar-mass moment of inertia, Ib · s 2 · ft (N · s 2 · m) U = Energy Variation, difference between the flywheel energy at maximum speed and at minimum speed, Ib · ft (J) N c = Number of cylinders. C u = Coefficient of energy variation. C s = Uniformity Speed Constant. K = 33 000 lb · ft · rpm/hp. WebFirst, determine the expression for the energy of a rotational system. Our flywheel will be a hollow cylinder, which gives us Mr 2 for moment of inertia. E-energy. I-inertia. M-mass. r-radius. w-angular velocity. Second, determine the limits to angular velocity due to material used: ρ = density, r = radius, ω = angular velocity, σ = tensile ...
