Steam enters a turbine with a pressure of 30 bar, a temperature of 400c, and a velocity of 160 m/s. saturated vapor at 1000c 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 the turbine and its surroundings occurs at an average outer surface temperature of 350 k. determine the rate at which entropy is produced within the turbine per kg of steam flowing, in kj/kg k. neglect the change in potential energy between inlet and exit.
