Q(3-3)A Brayton cycle with a reheating system using air as the working fluid has a pressure ratio of 7. The minimum and maximum temperatures in the cycle are 310 and 1150 K. The isentropic efficiencies is 75% for the both two turbines and 82% for the compressor. It is found that the temperature inlet at the low pressure turbine (LPT) is 1.2 of that at the exist of the high pressure turbine (HPT). The pressure at the second combustion chamber (C.C2) is 0.3 of that at the first combustion chamber (C.C1). Determine C.C1 C.C 2 Comp. HPT LPT The air temperature at the inlet of the first combustion chamber in K The air temperature at the exit of the pressure turbine in K The heat added at the first combustion chamber in k/kg The heat added at the second combustion chamber in kJ/kg
