Methane gas (CH4) at 25°C is burned steadily with dry air that enters the combustion chamber at 17°C. The volumetric analysis of the products on a dry basis is 5.20 percent CO2, 0.33 percent CO, 11.24 percent O2, and 83.23 percent N2. Determine
(a) The percentage of theoretical air used and
(b) The heat transfer from the combustion chamber per kmol of CH4 if the combustion products leave at 700 K.
