A mixture of fuel containing 0.480 mol CH4/mol, 0.300 mol C3 H8/mol, and 0.220 mol C3H12/mol at 58.0 °C and 131 kPa (gauge) enters a furnace at a rate of

89.0 L/min where it reacts with 15.8% excess air. Determine the volumetric flow rate of air to the furnace in SCFM (standard cubic feet per minute) by following the steps. Assume that the gases behave ideally. What is the molar flow rate of fuel entering the furnace? What is the molar flow rate of CH entering the furnace? What is the molar flow rate of C3 H8entering the furnace? What is the molar flow rate of C,H,, entering the furnace? What is the molar flow rate of the theoretical air required for the complete combustion of the fuel? What is the actual molar flow rate of air added to the furnace? What is the volumetric flow rate of air added to the furnacein standard cubic feet per minute?
