A simple impulse turbine has mean blade speed of 200 m/s. The nozzles are inclined at 20° to the plane of rotation of the blades. The steam velocity from nozzles is 600 m/s. The turbine uses 3500 kg/hr of steam. The absolute velocity at exit is along the axis of the turbine. Determine (i) the inlet and exit angles of the blades. (ii) the power output of the turbine, (iii) the diagram efficiency, (iv) the end thrust (per kg steam per second) and its direction .
