As shown in the figure below, a gas turbine power plant with regeneration is used. Air inlets the compressor with properties Pi= 1 bar and Ti= 25C, while the mass flow rate is 0.8 kg/s, and air outlets the compressor with a pressure of P= 5 bar. The isentropic efficiency of compressor and effectiveness of regenerator are 80% and 90%, respectively. It is noted that entire power produced by the high pressure turbine is consumed in the compressor. Also, net power output of the cycle is developed by the low pressure turbine. Both turbines have isentropic efficiencies of 90%, as the air enters high pressure turbine at 1300 K. Accordingly, find, Thermal efficiency of the cycle, P,=1 bar Regenerator 7 ww P, =5 bar 6 2 Combustor 4 T= 1300 K Qun Comp Turb, Turb, Wnet High Low pressure pressure 1 5 P =1 bar, T= 25 C
