An application of the linear isotherm regularity (LIR).
The linear isotherm regularity (LIR) for dense fluids is used to derive another regularity which is the isotherm [(partial differentialE/partial differentialv)T/rhoRT]v2 as a linear function of rho2, where E is the molar internal energy, (partial differentialE/partial differentialv)T is the internal pressure, and rho is the molar density (inverse of the molar volume v). The analytical expressions for the parameters of the latter regularity are obtained in terms of LIR parameters and reported for argon.
