This paper proposes an approach to calculate the specific thermodynamic energy and specific enthalpy of real gas. In the high-pressure air pneumatic system, the thermodynamic properties of the air which regarded as ideal gas would produce a large deviation to the actual value, thus seriously reducing the authenticity of the pneumatic parameters. In view of this, the specific residual thermodynamic energy and specific residual enthalpy of the high-pressure air were presented on the basis of modified corresponding state equation and virial equation which truncated to the third virial coefficient. In the specific enthalpy calculation for real gas, a difficult part of integration can be avoided by judiciously using advised residual functions. The true thermal physical property parameters of pneumatic system were obtained under the conditions of the wide variations of temperature and pressure.

When a gas is defined as the limiting one among real gases having zero radius of molecule, it was proved theoretically and by experimental data of the Joule-Thomson effect in various real gases that such a gas satisfied the whole well-known thermodynamic properties of the ideal gas. Thermodynamic properties of real gases at very low pressures were shown not to coincide with those of the ideal gas except with reference to the equation of state and specific heat capacity etc. and relations between real gases and the ideal gas were discussed. An empirical equation of state of real gases was reasonably shown to have to be of the virial expansion type.
