Just trying to locate specific heat constants with constant volume (not pressure), any ideas where to find this?
If you have a thermodynamic set of property tables it would be in the column with Cv (v should be a subscript) if you are looking at Cp that is the specific heat at constant pressure. They should be fairly close in most non-extreme conditions so becareful what your looking at
[itex]C_p[/itex] : Specific Heat at constant pressure [itex]C_v[/itex] : Specific Heat at constant volume Also [itex]C_p - C_v = R[/itex] [itex]\frac {C_p}{C_v} = lamda[/itex] where lamda = [itex]1 + \frac {2}{f}[/itex] Where f=degrees of freedon for monoatomic gas , f=3 for diatomic gas , f=3 You can solve for two expressions at the top to get Cp BJ
And that's only at around room temperature's where the vibrational degree of freedom is absent. At high temperatures, f will be 7 for diatomic gases.
