A steam turbine operates with 5000 kg/hr of steam at 4000 kPa and 480 deg C and exhausts steam at 100 kPa. A) Using a mollier diagram, and assuming the turbine is adiabatic and operates reversibly what is: i) the exit temperature and ii)power generated by the turbine? (answer is 100 C and -1180 kW) B) If the turbine efficiency is .75: i) what is exit temp? ii) what is moisture content of exhaust? iii) power generated by turbine? iv) at what rate would entropy be generated within turbine? v) assuming the temp of the surroundings T(sigma)=300K what is lost work in kJ/kg of steam?
