Question
Considering the properties as shown, calculate the power needed to overcome viscous resistance.
Remember from prior subjects:
U, Velocity = Radius of the movable part x Angular velocity = (r)(ω)
T, Torque = Force x moment arm, which is the radius of the movable part = F(r)
P, Power = T(ω)
1 revolution = 2π
ω = 2π(N) where N is revolution per unit of time
