The compressor turbine of a simple gas turbine each have isentopic efficiencies of 90%. The compressor pressure ratio is 12. The minimum and maximum temperatures are 290K and 1400K, respectively. Determine:
(a) the net work per unit mass of air flowing in kJ/kg
(b) the heat rejected per unit mass of air flowing in kJ/kg
(c) the thermal efficiency of the same quantities evaluated for an ideal cycle
