The steam from the nozzles of a single wheel impulse turbine is 600m/s and at 20degree to the plane of the wheel. The blade wheel rotates at 3000rev/min and the mean blade radius is 590mm. The axial velocity of the steam at exit from the blade is 164m/s and the blades are symmetrical. Calculate 1: The blade angles; 2: The diagram work per unit mass flow rate    steam. 3: The diagram efficiency.
