Question
(a) Show that the efficiency of a free jet striking normally on a series of flat plates mounted on the periphery of a wheel never exceeds $50\%$.
(b) A jet of water moving at $25\text{ m/s}$ impinges on a symmetrical vane shaped to deflect the jet through an angle of $120^\circ$ when the vane is stationary. If the vane is moving at $10\text{ m/s}$, find the angle of the jet so that there is no shock at inlet. Also determine the absolute velocity at exit. Neglect friction of vanes.
