Five liters/s of water enter the sprinkler shown in the figure, along the axis of rotation. The cross-sectional area of each of the three nozzle exits normal to the relative velocity and it is 18 mm2. 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) =0, (b) =30, (c) = 60
