# A jet of water of 100 mm diameter strikes a curved plate at the center with a velocity of 15 m/s. The curved plate is moving with a velocity of 7 m/s in the direction of the jet. The jet is deflected through an angle of 150°. Assuming the plate to be smooth, find: (a) Force exerted on the plate in the direction of the jet (b) Power of the jet (c) Efficiency of the jet (d) What happens to the efficiency of the jet if the plate is stationary.
