If the isentropic efficiencies of the compressor and turbine are 0.8 and 0.9, find the following. Assume the working fluid is air, an ideal gas with constant specific heats. Use k=1.4 and R=287 J/kgK.
1) Work per mass to the compressor [kJ/kg]
2) Work per mass from the turbine [kJ/kg]
3) Net work per mass from the cycle [kJ/kg]
4) Back work ratio [-]
5) Heat transfer per mass to the working fluid from the combustor[kJ/kg]
6) Cycle Efficiency [-]
7) Ideal Brayton cycle efficiency [-]
8) Carnot Efficiency for these conditions [-]
