If the specific heats of the working fluid are constant and the value ...
Is known, then the specific heat at constant pressure (Cp) and the specific heat at constant volume (Cv) can be determined.

The specific heat ratio (γ) is the ratio of Cp to Cv, and is defined as:

γ = Cp / Cv

If the value of γ is known, the specific heat at constant pressure (Cp) can be calculated as:

Cp = γ * Cv

Similarly, the specific heat at constant volume (Cv) can be calculated as:

Cv = Cp / γ

So, if the specific heats of the working fluid are constant and the value of specific heat ratio is known, both Cp and Cv can be determined using the formulas mentioned above.
