In this paper it is shown by a comparison with reliable experimental data in a wide range of pressures and temperatures that the Redlich–Kwong equation of state fits well the distinctive characteristics of the compressibility coefficient, the throttling factor, and the reduced difference of specific isobaric and isochoric heat capacities. It is found that this equation corresponds to the inequalities required to ensure hyperbolicity of the set of equations of real gas flows in pipelines.
