Steam enters a turbine with a pressure of 30 bar, a temperature of 440 C, and velocity of 160 m/s. Saturated vapor at 100C exits with a velocity of 100 m/s. at steady state, the turbine develops work equal to 540 Kj per Kg of steam flowing through the turbine. Heat transfer between turbine and its surroundings occurs at an average outer surface temperature of 350 K.
