An air standard gas turbine engine operates on an overall pressure ratio of 4 and between the temperature limits of 70 F and 1600 F. The efficiencies of compressor and turbine are 0.82 and 0.92, respectively. To modify, a regenerator of effectiveness 0.65 is added and two stage of compressor with intercooler is inserted and two-stage turbine with reheater is inserted. (a) Assuming constant specific heats, evaluate the compressor work (b) calculate the turbine work (c) calculate the thermal efficiencies
