the compressor and turbine of a simple gas turbine have isentropic efficiencies of 80% and 90% respectively. The compressor pressure ration is 12. The minimum and maximum temperatures are 290 K and 1400 K, respectively. On the basis of air-standard analysis, compare the values of: a)net work per mass of air flowing b)the heat absorbed in the combustion chamber per unit mass of air flowing c) thermal efficiency with the same quantities evaluated for an ideal brayton cycle.
