Consider the reaction of air with a hydrocarbon jet fuel composed of roughly 1.9 times as many hydrogen atoms as carbon atoms. the thermal yield for this fuel is 43 mj/kg-k. the reactant side of the chemical equation can be written as:
ch1.9 + x (o2 + 3.76 n2 ) → + +

determine x for a stoichiometric fuel to air ratio.
what is the ratio of the mass of fuel to the mass of the air for this reaction?
consider bulk combustor equivalence ratios ranging from 0.1–1.0. plot the temperature of the combustion mixture using an initial air temperature of 600 k. assume that the reactions are all complete regardless of the equivalence ratio
