1. Stationary Gas Turbine A stationary gas turbine operates on an ideal Brayton cycle that has a pressure ratio of 8 . The air properties at the start of the compression are 14.5psi and 77F. The maximum cycle temperature is 2012F. Determine (a) the thermal efficiency, th (b) the compressor work per unit mass in [lbft/lbm], (c) the heat added per unit mass in [Btu/lbbm], and (d) the turbine work per unit mass in [lbft/lbm]. (Note that for air cp= 0.241Btu/lbbR and =1.4) th=0.448wc=81.7103lbft/lbmqin=361Btu/lbmwt=208103lbft/lbm
