# Question Solved1 Answer 1.       A 15 cm diameter jet of water with a velocity of 15 m/s strikes a plate normally. If the plate is moving with a velocity of 6 m/s in the direction of the jet,   (a) calculate the work done per second on the plate and the efficiency of energy transfer by the jet.   (b) What would be the efficiency if the jet impact is on a series of blades mounted on a wheel? 2.       *A two-dimensional jet of water impinges on a plane at an angle θ to the normal to the plane. If the jet splits in to two streams of discharges in the ratio 1: 2.5, calculate the angle θ.
