Liquid propane enters a combustion chamber at 25ºC at a rate of 0.05 kg/min where it is mixed and burned with 50 percent excess air that enters the combustion chamber at 7ºC. An analysis of the combustion gases reveals that all the hydrogen in the fuel burns to H2O but only 90 percent of carbon burns to CO2, with the remaining 10 percent forming CO. If the exit temperature of the combustion gases is 1500 K, determine : i) The mass flow rate of the air ii) The rate of heat transfer from the combustion chamber |
