1.A free water jet has a velocity of 10 m/s and an area of 0.01 m2. This jet impinges normally on a vertical plate that is moving with a velocity of 5 m/s against the direction of the jet. The force on the plate due to this impingement of the jet, by considering the density of water r = 1000 kg/ m3, is (a) 2250 N (b) 1000 N (c) 500 N (d) 250 N 2. A free water jet of 0.01 m2 area and of 20 m/s velocity impinges normally on a stationary vertical plate. If the plate is to move in the direction of the jet at a velocity of 5 m/s, what increase in the discharge at the nozzle would keep the force
