Methane is burned with air and the exhaust products are measured (on a dry, volumetric basis) to be 4.8% CO2, 0.12% CO, 12.25% O2, and balance N2. Determine (a) the air-tofuel ratio (mass based) (5 points), (b) equivalence ratio (5 points) (c) the percent theoretical air (%) (5 points), (d) the percent excess air (%) (5 points), and (e) exhaust dew point (°C) if the exhaust is at 1 atm (5 points). (25 points)
