4. Mono-Methyl Hydrazine (CH6N2) is to be used as a fuel, with Nitrogen Tetroxide (N2O4) as an oxidizer, in a combustor, a. What is the Stoichiometric Oxidizer to Fuel ratio on a Mass basis? [5] b. Compute the resulting Adiabatic Flame Temperature. [15] Take the initial conditions to be at Standard Temperature and Pressure. Assume Complete Combustion and Constant Specific Heats (to obtain the required Enthalpy values). Relevant properties at Standard Temperature and Pressure are given in the Table below: Species Cp CO2 H2O N2 CH6N2 N2O4 37.2 33.4 29.1 N/A N/A (KJ/kmol-K) H (KJ/kmol) -393,500 -241,800 0 54,200 -19,500 |
