Liquid propane (C₃H₈) enters a combustion chamber at 25C at a rate of 0.07 kg/min where it is mixed and burned with 40 percent excess air that enters the combustion chamber at 7C. An analysis of the combustion gases reveals that all the hydrogen in the fuel burns to H0 but only 75 percent of the carbon burns to CO, with the remaining 25 percent forming CO. determine (a) the balanced equation for actual combustion process and (b) the mass flow rate of air.
