Q 1: A jet of water of diameter 100 mm strikes a curved plate at its 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 smooth find: (i) Force exerted on the plate in the direction of the jet. (ii) Power of the jet, and (iii) Efficiency.
