Liquid propane (C3H8) enters a combustion chamber at 25°C at a rate of 1.2 kg/min where it is mixed and burned with 150 percent excess air that enters the combustion chamber at 12°C. If the combustion gases consist of CO2, H2O, CO, O2, and N2 that exit at 1200 K and 2 atm, determine
(a) The equilibrium composition of the product gases
(b) The rate of heat transfer from the combustion chamber. Is it realistic to disregard the presence of NO in the product gases?
