Using sensible enthalpies evaluated from property tables (Appendix A) Determine the adiabatic flame temperature for constant-pressure combustion of a stoichiometric propane-air mixture assuming reactants at 298K, no dissociation of the products and: a.
WebThe ratio of specific heats γ is the ratio of the heat capacity at constant pressure, C p, to the heat capacity at constant volume, C v. When using the ideal gas law to describe a fluid, specifying γ is sufficient to evaluate C p. For common diatomic gases such as air, γ = 1.4 is the standard value. WebIf specific heat is expressed per mole of atoms for these substances, none of the constant-volume values exceed, to any large extent, the theoretical Dulong-Petit limit of 25 J/ (mol·K) = 3 R per mole of atoms (see the last column of this table).
