Question
Steam enters the first-stage turbine shown in the figure at 40 bar and 4500C with a mass flow rate of 40,000 kg/hr. Steam exits the first-stage turbine
at 20 bar and 400°C. The steam is then reheated at constant pressure to 500°C before entering the second-stage turbine. Steam leaves the second
stage as saturated vapor at 0.6 bar. Assume steady state operation and ignore stray heat transfer and kinetic and potential energy effects.
