<jats:p>Corrections to the approximate hard sphere dense fluid transport theory of Enskog, determined by the method of molecular dynamics, have been incorporated in analytical expressions for the exact coefficients of self-diffusion, viscosity, and thermal conductivity in hard sphere systems in terms of the molar volume at densities greater than one-half the close packed density. Application of these equations to recent experimental transport coefficient data for liquid carbon tetrachloride shows that these data can be satisfactorily interpreted on the basis of this simple model with temperature- and pressure-dependent molecular diameters. Self-diffusion and viscosity data for liquid methane are also adequately accounted for in terms of the hard sphere theory, but for argon the calculated self-diffusion coefficients are somewhat greater than recent experimental values.</jats:p>
