We evaluate the intrinsic shear and bulk viscosities of a solution or suspension of hard-sphere solute in a hard-sphere solvent. We use the ideas, developed in the preceding paper, of the generalized boundary condition descriptive of the solute--solvent binary collision in the presence of the solvent treated as a continuum. Via an appropriate choice of the effective core radius and effective mass of the binary collision, we obtain analytically simple expressions that yield the correct hydrodynamic results in the limit K = l/sigma/sub 11/..-->..0 as well as a reasonable approach to the Enskog result when K is large. Here l and sigma/sub 11/ are the mean free path in solvent and size of the solute particle, respectively. Our results also show for the case of a high-density solvent remarkable agreement with hydrodynamic results over a wide range of solute particle size.
