Liquid propane (C_3H_8) enters a steady-flow combustion chamber at 25 Degree C, and 6 atm at a rate of 0.8 kg/min. It is burned with 150 percent excess air that is compressed and preheated to 400 K and 6 atm before entering the combustion chamber. The products of the combustion enter a gas turbine at 1200 K and 6 tam and leave at 700 K and 1 atm. The adiabatic efficiency of the turbine is 80%. The combustion process is...
