6.9 One stage of an impulse turbine consists of a converging nozzle and one
ring of moving blades. The nozzle angles are 22° and the blade angles are
35°. The velocity of steam at the exit from the nozzle is 650 m/s. If the
relative velocity of steam to the blades is reduced by 14% in passing
through the blade ring, find the diagram efficiency and the end thrust on the
shaft when the blade ring develops 1650 kW.
