The nozzles of the impulse stage of a turbine reccive steam at 1S bar and 300 C and discharge it at 10 bar. The nozzle efficiency is 95% and the nozzle angle is 20°. The blade speed is that required for maximum work, and the inlet angle of the blades is that required for entry of the steam without shock. The blade exit angle is 5° less than the inlet angle. The blade velocity coefficient is 0.9. Calculate for a steam flow of 1350 kg/h: (i) the diagram power; (ii) the diagram efficiency. 10 1 kly.86
