Nature of problem:
The transport properties of a gas mixture are the thermal conductivity, viscosity and the diffusion and thermal diffusion coefficients. The program calculates these transport properties.

Solution method:
The transport properties may be expressed in terms of coefficients in the Sonine polynomial expansions of the unknown coefficients occuring in the solution of the perturbed form of the Boltzmann equation. The program solves matrix equations for the coefficients and hence calculates the transport properties.

Up to ten gases may be included in the mixture. The effect of inelastic collisions of molecules is not included and elastic collisions are described by the Lennard-Jones (12-6) potential.

Forty seconds for compilation and five seconds for execution on the Leeds 1906A.
