Octane, C8H18, is burned with theoretical amount of air at 500 kPa. Determine
(a) The air fuel ratio on a mole basis.
(b) The air fuel ratio on a mass basis.
(c) IF the products are cooled at a constant pressure of 500 kPa, at what temperature will dew start to form?
(d) Suppose the products are cooled below the dew point temperature so that all the water from the products are removed (neglect any vapor which may still be present at very low amount). What would be the volume fraction of CO2 in the dry products? If you have a smog test report of your gasoline burning car at hand, compare the CO2 amount (in percent).
