The compressor and turbine of a simple gas turbine each have isentropic efficiencies of 80%. The compressor ratio is 12. The minimum and maximum temperatures are 290 K and 1400 K, respectively. On the basis of an air-standard analysis, compare the values of (a) the net work per unit mass of air flowing (in kJ/kg), (b) the heat rejected per unit mass of air flowing (kJ/kg), and (c) the thermal efficiency to the same quantities evaluated in an ideal cycle.
