Q2/ Answer the following question: A laboratory engine uses the heptan (C₂H₁6) as a fuel. A dry analysis of the exhaust of this engine gives the following volumetric percentages: CO₂= 5.2%, CO 8.1%, and O₂ = 4.2%. Calculate the equivalence ratio at which the engine is operating. The molecular weights of air and heptan fuel are 29 and 100 respectively. E
