Steam enters a turbine with a pressure of 3 mpa, a temperature of 400°c, and a velocity of 160 m/s. saturated vapor at the turbine produces 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 boundary temperature of 350 k. changes in kinetic energy of the steam are not negligible, but changes in potential energy are. (ge=1) (a) at steady state, what is the rate of heat transfer to the surroundings? (b) what is the rate at which entropy is produced within the turbine per kg of steam? 100°c exits with a velocity of 100 m/s. at steady state,
