A split-shaft gas turbine has its power turbine supplied with 150 lb/sec of gas at 50 psia and 1100 F and exhausts the gas from the power turbine at 16 psia and 800 F, respectively. The power turbine exhaust is led through a counter-flow regenerator where the gas temperature is lowered another 40 F. The compressor pressure ratio is 12, and the inlet conditions are 14.6 psia and 60 F. Compressor discharge temperature is 740 F. Using air tables calculate: (A) The power turbine efficiency % Ans: 74.5% (B) The compressed air temperature leaving the regenerator, F Ans: 780 F (C) the regenerator effectiveness, Btu/lb Ans: 66.7%
