“…is the fugacity of the hypothetically pure incompressible liquid ethane at the temperature and pressure of the system. It was computed from the following equation -P°f (P.T) 1 P (P'i.T) exp lwip-p'l (3) where P°is the vapor pressure of__component 1 at the temperature of the system, T, and Vi is the partial molar volume of ethane in a dilute solution at temperature T.…”

of viscosity given by the present correlation and the values computed by Dean and Stiel's (3)equations. This may be attributed to inherent errors in the method of determination of the pseudocritical constants (3). In Figure 1, a regular trend is noticed between the limits of the two pure components. This clearly brings out the effect of mixture composition on viscosity of the Freon-12-Freon-22 vapor mixture system. CONCLUSIONThe present correlation facilitates design of engineering systems, as viscosity information on pure Freon-12 and Freon-22 vapors and their mixtures may be obtained readily. The determination of viscosity, however, requires an accurate knowledge of the temperature-dependence of viscosity at zero density. For engineering purposes, it may be convenient to use the atmospheric viscosity values. These atmospheric viscosity values may be calculated for pure components by the correlation of Witzell and Johnson (20) and for mixtures by Herning and Zipperer's (4) equation or by Wilke's (19) equation.

A reduced density correlation for the gaseous and liquid regions of ethane has been developed from all the experimental PVT data available in the literature for this substance. Saturated vapor and liquid densities reported for methane, propane and n-butane were utilized to establish the rectilineardiameter line for ethane. This line was then used with the saturated-vapor data for ethane to produce the saturated envelope for this substance. Most of the saturated liquid data reported for ethane were found to be inconsistent with the saturated-liquid curve resulting from this study.The correlation covers the regions 0.65 < TR < 6.0 and 0 < P R < 15. For regions for which no experimental data have been reported, the isobars of the correlation were extended by the use of the theorem of corresponding states. This correlation is presented both on rectilinear and log-log coordinates.
