Question: The Answer Should Be: Q = 360,460 Btu/lbm and S(p) = 1364.79 Btu/R Methane, CH4, enters a furnace at 40F and 14.7 psia while 300%
The Answer Should Be: Q = 360,460 Btu/lbm and S(p) = 1364.79 Btu/R

Methane, CH4, enters a furnace at 40F and 14.7 psia while 300% theoretical air enters through another inlet at 14.7 psia and 50F. The products of complete combustion leave at 537R (Rankine degrees) and 14.7 psia. (a) Calculate the heat interaction per lb-mole of CH4. (b) Find the absolute entropy of the products as they leave the furnace
