 Problem 3 (20 points) Consider a blend containing ' a '

Problem 3 (20 points) Consider a blend containing ' a ' and ' b ' moles of two hydrocarbon fuels (Cx1Hy1 and Cx2Hy2). The mole fraction of various species in the fuel-air mixture are computed using the following stoichiometric equation: aCx1Hy1+bCx2Hy2+c(O2+3.76N2)(ax1+b.x2)CO2+0.5(ay1+by2)H2O+(3.76.c)N2 (a) Derive the equation for c (the number of moles of O2 ) by using the mass balance for O. (b) Use a=b=0.5, and calculate the value of c=3.5 for a fuel mixture of methane and propane. (c) Calculate the mole fraction of H2O
