Question: Liquid propane (C3H8) enters a steady-flow combustion chamber at 25C and 1 atm at a rate of 0.4 kg/min where it is mixed and burned

Liquid propane (C3H8) enters a steady-flow combustion chamber at 25°C and 1 atm at a rate of 0.4 kg/min where it is mixed and burned with 150 percent excess air that enters the combustion chamber at 12°C. If the combustion products leave at 1200 K and 1 atm, determine (a) the mass flow rate of air, (b) the rate of heat transfer from the combustion chamber, and (c) the rate of entropy generation during this process. Assume T0 = 25°C.
