An adiabatic steam turbine in an electric power plant is designed to accept steam at 5000 kPa and 600°C and discharge the steam at 101.3 kPa. a) What is the exit temperature of the steam and the work produced (per kg of steam) if the turbine operates adiabatically and reversibly? b) If the turbine operated adiabatically but irreversibly, with an isentropie efficieney of 80 %, what would be the exit temperature and the work produced (per kg of steam)? c) For part b, what is the entropy generation Sa?
