For Problems 1 & 2: (0.015 + y/800) kg/s of liquid octane (C8H₁8) with airentering a combustion chamber at 1.0 atm at 25°C and at a steady rate. Ifthe mixture is lean (too much air) then assume that there is completecombustion with reactants consisting of: N2, O₂, CO₂, and H₂O. On the otherhand, if the mixture is rich (too much fuel) assume that there will be someCO in the exhaust with the exhaust consisting of N₂, CO₂, CO, and H₂O.Assume all reactants are in the gaseous phase (no liquid water in theexhaust). 1) If the combustion is rich, with (70+y/4)% theoretical air, find thefollowing: The Air Fuel ratio: . The partial pressure of the water vapor. . The dew point of the exhaust. Qout if the exhaust exits at 127°C.
