    What is the composition and molar flowrate [in mol/s] of the intake air....?

    ch4 gas enters a furnace at a rate of 100mol/s and combusted with humid air flowing at 50,000 SCFM(standard ft^3/min). The intake air is 25 degrees C, 1atm with a relative humidity of 80%. Assume that air is ideal and that dry air is 79mol% N2 and 21mol% O2. a) What is the composition and molar...
