3)PARAMETRIC: Liquid octane (C8H18) at 298 K & 1 atm enters a well-insulated combustion chamber and burns with air. For steady-state operation and assuming complete combustion, plot the following: a)

Products temperature vs. % theoretical air (100% - 400%), if air enters at constant 298 K. b) Products temperature vs. inlet-air temperature (298-600 K) at constant 120% theoretical air.
