A jet of water 50 mm in diameter with a velocity of 20 m/s strikes a flat plate inclined at an angle of 30° to the axis of the jet. Determine

(i) the normal force exerted on the plate when the plate is stationary

(ii) the normal force exerted on the plate when the plate is moving at 5 m/s in the direction of the jet

(iii) the work-done on the plate and the efficiency for case (ii).
