摘要

An equation for a moderately dense gas transport coefficient, derived in the preceding article from time correlation function theory, is specialized to the estimation of the coefficients of viscosity and thermal conductivity. These equations include the first order in density correction to the transport coefficient, but are restricted to being valid only for repulsive potentials. It is shown that the resulting expressions are, within a series of analogous approximations, identical to those obtained by solving the generalized Boltzmann equation.
