13.75 Air enters the compressor of a simple gasturbine power plant at 70F, 1 atm, is compressed adiabatically to40 lbf/in.2, and then enters the combustion chamber where it burnscompletely with propane gas (C3H8) entering at 77F, 40 lbf/in.2anda molar flow rate of 1.7 lbmol/h. The combustion products at 1340F,40 lbf/in.2 enter the turbine and expand adiabatically to apressure of 1 atm.The isentropic compressor efficiency is 83.3% andthe isentropic turbine efficiency is 90%. Determine at steadystate
(a) the percent of theoretical air required.
(b) the net power developed, in horsepower.
