Steam enters a turbine operating at steady state at 6 mpa, 600°c with a mass flow rate 125 kg/min and exits as a saturated vapor at 20 kpa. the turbine produces energy at a rate of 2 mw. kinetic and potential energy effects are negligible. the rate of heat loss from the turbine occurs to the air around the turbine at 27°c. a. what is the rate of entropy production for within the turbine? b. what is the isentropic efficiency of the turbine?

= 6MPa
= 
= 3660kJ/kg
= 7.17Kj/kgK
= 20kPa
= 1
= 7.91kJ/kgK
= 2610kJ/kg
= 20kPa
=s_1
= 2360kJ/kg
