(Answered) : Problem 5 9 El Wakil S Powerplant Technology Book Rateau Turbine Operating 1000 Psia 1000 Q28207397

This is problem 5-9 from El-Wakil’s Powerplant Technology book– a Rateau turbine operating between 1000 psia and 1000degFahrenheit and 1 atm has symmetrical blades, nozzle angles of20°, nozzle efficiencies of 97 percent, and velocity coefficientsof 0.97. (The same data as that for the Curtis stage in Prob. 5-8).Calculate (a) the number of stages necessary to limit the optimumblade velocity to that of the Curtis stage (1009.6 ft/s), (b) thework of each stage, in Btus per pound mass, (c) the absolute steamvelocity leaving the first stage. Problem 5-8 for this question –steam enters a Curtis impulse stage at 1000 psia and
