Mechanical Engineering
This is problem 5-5 from El-Wakil’s Powerplant Technology book-- steam expands ideally in a turbine from 2500 psia and 1000degFahrenheit to 1 psia. Compare the maximum steam velocities andthe number of stages required by (a) a velocity-compounded impulseturbine, (b) a pressure-compounded impulse turbine, and (c) a 50percent reaction turbine if the optimum blade velocity may notexceed 885 ft/s in any of them. Take all nozzle angles to be25°.
