9. A certain natural gas has the following volumetric analysis: 73.4% CH4,
8%C2H6, 5% C3H8, 2%C4H10, 1.8% H2, 8% N2, 0.8% 02 and 1% CO2.
This gas is now burned with the 100% excess air that enters the combustion
chamber at 18°C, 1 atm, and 75 percent relative humidity. Assuming complete
combustion and a total pressure of 1 atm, determine the
a. air- fuel ratio
b. dew-point temperature of the products
