Amixture of fuel containing 0.540 mol ch4/mol, 0.330 mol c3h8/mol, and 0.130 mol c5h12/mol at 56.0°c and 135 kpa (gauge) enters a furnace at a rate of 87.0 l/min where it reacts with 16.6% 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.
a) what is the molar flow rate of fuel entering the furnace?
b) what is the molar flow rate of ch4 entering the furnace?
c) what is the molar flow rate of c3h8 entering the furnace?
d) what is the molar flow rate of c5h12 entering the furnace?
e) what is the molar flow rate of the theoretical air required for the complete combustion of the fuel?
f) what is the actual molar flow rate of air added to the furnace?
g) what is the volumetric flow rate of air added to the furnace in standard cubic feet per minute?
