Five liters/s of water enter the rotor shown in Video V5.10 and Fig. P5.83 along the axis of rotation. The crosssectional area of each of the three nozzle exits normal to the relative velocity is \(18 \mathrm{~mm}^{2}\). How large is the resisting torque required to hold the rotor stationary? How fast will the rotor spin steadily if the resisting torque is reduced to zero and

(a) \(\theta=0^{\circ}\),

(b) \(\theta=30^{\circ}\),

(c) \(\theta=60^{\circ}\) ?
