Problem 3 (20 points) a steam turbine operates adiabatically between pressures 25 and 3 mpa. the inlet flow consists of 22 kg/s of super-heated water vapor at 500 c, whereas the exit flow is saturated vapor. determine: a. the power developed by the turbine. b. the isentropic efficiency of the turbine. hint: kinetic and potential energy can be neglected.
