Steam enters the first-stage turbine shown in the figure at 40 bar and 500°C with a mass flow rate of
110000 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
