Homework #5 Due Thursday November 30 in Class\ Species H\ f,298K [kJ/mol] cp [kJ/(mol K)]\ C8H18 -249.93 not needed\ C10H22 -301.0 not needed\ H2 0.0 not needed\ O2 0.0 0.035\ H2O -241.8 0.041\ CO2 -393.5 0.054\ N2 0.0 0.033\ 1. Lets assume that Jet-A fuel can be represented by the molecular structure, C12H23. We\ consider its combustion with dry air.\ a) Write the equation for a stoichiometric chemical reaction of this fuel with air.\ b) Determine the stoichiometric (theoretical) fuel-air ratio.\ c) Write a balance reaction equation for combustion with an equivalence ratio of 0.65.\ d) What would be the stoichiometric fuel-oxygen ratio for combustion of the fuel in pure\ oxygen?\ Note that the specific enthalpy of vaporization of water is 2.443 MJ per kg of water.
