A 7.5 cm diameter jet having a velocity of 30 m/s strikes a flat plate,the normal of which is inclined at 45° to the axis of the jet. find the normal pressure on the plate: (i) when the plate is stationary and (!i) when the plate is moving with a velocity of 15 m/s and away from the jet.Also determine the power and the efficiency of the jet when the plate is moving.
