(30 pts) Liquid propane enters a combustion chamber at 25 °C at a rate of 1.2 kg/min where it is mixed and burned with 150% excess air. The air enters

the combustion chamber at 12 °C. The combustion products exit at 1200 K.3. Assuming complete combustion and no dissociation, (a) Determine the mass flow rate of the air (b) Determine the rate of heat transfer from the combustion chamber. Include as part of your solution an H-T diagram, illustrating the combustion process.
