1. Exhaust gas at 400C and 1 bar from internal-combustion engines flows at the rate of 125mol/s into a waste-heat boiler where saturated steam is generated at a pressure of 1200kPa. Water enters the boiler at 20C(Ta), and the exhaust gases are cooled to within 10C of the steam temperature. The heat capacity of the exhaust gases is Cp/R= 3.34. The steam flows into an adiabatic turbine and exhausts at a pressure of 25kPa. If the turbine efficiency is 72% a.) What is Ws, the power output of the turbine? (5pts) b.) What is the thermodynamic efficiency of the boiler/turbine combination? (5 pts) c.) Determine the entropy generation rate for the boiler and for the turbine. (10 pts) d.) Express W lost(boiler) and W lost(turbine) as fractions of W ideal, the ideal work of the process. (10 pts)
