Consider a Brayton cycle with two stages of compression (intercooling between) and two stages of expansion (reheat between). The pressure ratio across each compressor stage and each turbine stage is 8 to 1. The pressure at the entrance to the first compressor is 14 psi, the temperature entering each compressor is 70°F, and the temperature entering each turbine is 2000°F. A
regenerator is also incorporated into the cycle with an effectiveness of 70%. The compressors and
turbines all have isentropic efficiencies of 85%
Determine: Using constant specific heat method
1) The compressor work in Btu/lbm
2) The turbine work in Btu/lbm
3) The thermal efficiency of the cycle.
4) Draw the T-s Diagram for this cycle
