AbstractA simple equation of state is used to calculate the bulk modulus, Joule-Thomson inversion temperature, and isobaric expansivity of dense fluids (with density greater than the Boyle density). The EOS predicts the following regularities: (i) the linearity of the bulk modulus versus pressure for each isotherm of a dense fluid for a range of about 100 MPa for subcritical fluids and about 1000 MPa for supercritical fluids, (ii) the linearity of bulk modulus with respect to temperature for each isochore, and (iii) the linearity of inverse isobaric expansivity with pressure for each isochore. The regularities have been found to be consistent with experimental observations. The calculated Joule-Thomson inversion temperature shows good agreement with experimental data in the range of validity of the EOS.
