Thermodynamic properties of mixtures

Measurements on the viscosity of liquid carbon dioxide as a function of temperature, pressure, and density are reported and discussed. The measurements are carried out over the entire liquid range at pressures up to 200 kgf/cm2. The viscosity coefficients have been evaluated by measuring the electrical characteristics of a torsionally vibrating quartz crystal immersed in the liquid. The obtained results have been used to test the Arrhenius equation lnη = A + B / T, the Doolittle free volume equation lnη = A′ + B′ρ / (ρ0 − ρ), and the Batschinski equation ηρ−1 = Cη + D.
