Notes: Clearly specify your basis for solution. You do not have to present a DOF analysis. A gaseous fuel at 25C and 15mmHg gage pressure is sent to a furnace at the rate 210 m3/min and burned with 50% excess air. The fuel is composed of 10%CH4,4%C3H8,20%H2, 46%CO,5%CO2,8%O2, and 7%N2. The air for combustion is at 25C and 1.1atm abs and has 60% relative humidity. The stack gas leaves the furnace at 400C and under a draft of 10 cmH2O. The barometer shows 745mmHg. Calculate, assuming complete combustion, a) The Orsat gas composition of the stack gas in molar percentage, b) The dew point of the stack gas, c) The ratio of moles of dry stack gas to the moles of dry air, d) The volumetric flow rate of the wet stack gas in units of SCMH
