In an air standard gas turbine cycle, air at 14.5 psia and 70 F is first compressed to 80 psia in a compressor of 82 percent efficiency. The hot air leaving the combustion chamber at 1250 F is expanded back to 14.5 psia in a turbine of 85 percent efficiency. If a regenerator is inserted into the cycle to heat the air leaving the compressor to 650 F, determine the thermal efficiency of the cycle and the effectiveness of the regenerator.
