Reverse Combustion Analysis Octane
Octane \left(\mathrm{C}_{8} \mathrm{H}_{18}\right) is burned with dry air. The volumetric analysis of the products on a dry basis is (Fig. 15-13)
\mathrm{CO}_{2}: 10.02 percent
\mathrm{O}_{2}: 5.62 percent
\mathrm{CO}: 0.88 percent
\mathrm{N}_{2}: 83.48 percent
Determine (a) the air-fuel ratio, (b) the percentage of theoretical air used, and (c) the amount of \mathrm{H}_{2} \mathrm{O} that condenses as the products are cooled to 25^{\circ} \mathrm{C} at 100 kPa.
