cp/Rgas = a0 + (a1/T2)×e-a2/T + a3×Y2 + [a4 - a5 /(T - a7)2]×Y8
| Y = | 0, | T ≤ a7 |
| (T - a7)/(T - a6), | T > a7 |
where Rgas = universal gas constant
The basis for this functional form is discussed in [37].
Please note that the equations above are expressed in terms of heat capacity and not in the necessary integral form.
