A mixture of fuel containing 0.530 mol CH4/mol, 0.330 mol C3H8/mol, and 0.140 mol C5H12/mol at 60.0°C and 125 kPa (gauge) enters a furnace at a rate of 91.0 L/min where it reacts with 17.4% excess air. Determine the volumetric flow rate of air to the furnace in SCFM (standard cubic feet per minute) by following the steps below. Assume that the gases behave ideally.
What is the molar flow rate of fuel entering the furnace? (in mole fuel/min)
What is the molar flow rate of CH4 entering the furnace? (in mole CH4/min)
What is the molar flow rate of C3H8 entering the furnace? (in mole C3H8/min)
What is the molar flow rate of C5H12 entering the furnace? (in mol C5H12/min)
What is the molar flow rate of the theoretical air required for the complete combustion of the fuel? (in mol air/min)
What is the actual molar flow rate of air added to the furnace? (in mol air/min)
What is the volumetric flow rate of air added to the furnace in standard cubic feet per minute? (in SCF/min)
