3. Thermal capacities of real fluids

In principle, knowledge of a fluid's equation of state enables us to determine the deviation of its thermodynamic properties (residual quantities) from the perfect state as a function of temperature and pressure.

with the exponent ^• standing for perfect gas,

where R stands for residual.

The principle behind this type of calculation is briefly explained in the article Calcul des constantes thermodynamiques ( [K 540] ).
