The LMNO Engineering calculation takes the user input temperature and extracts viscosity We don't collect information from our users. In the critical region the viscosity shows a similar abnormal behaviour as found for the heat conductivity of argon. 0000005323 00000 n Cookies are only used in the browser to improve user experience. 0000010134 00000 n 0000002955 00000 n For the thermodynamic properties, a classical equation for the molar Helmholtz energy, which contains terms multiplied by the exponential of the quadratic and quartic powers of the system density, is used. 0000008648 00000 n By expressing these rates in dimensionless form (i.e., in terms of Stanton number and Prandtl number), an empirical correlation similar to the submerged jet model of Brown and Sonin (1989) was derived. The reference The results are employed to distinguish between conflicting data sets that already exist in the literature and that have inhibited accurate representations of the viscosity of this important fluid.

Measurements on the viscosity of liquid carbon dioxide as a function of temperature, pressure, and density are reported and discussed. 0000016467 00000 n The measurements are carried out over the entire liquid range at pressures up to 200 kgf/cm2. The viscosity of carbon dioxide mainly affects the axial pressure transmission by generating flow friction. The excess molar volumes, v(m)(E), of the mixtures were calculated and plotted as a function of temperature and pressure. Only emails and answers are saved in our archive.
