From the solution of the Boltzmann‐equation, transport properties of gas‐plasmas in a temperature range from 1 000 K to 40 000 K and gas pressures from 0.1 bar to 100 bar can be determined by the described procedure. Although only the dynamic viscosity, thermal and electrical conductivity for three gas‐plasmas are presented in this paper, other transport properties like binary, general or thermal diffusion coefficients can be computed with the described procedure. The evaluated values may be slightly incorrect, if in the case of high pressures and low temperatures, the basic assumptions for Enskog's solution of the Boltzmann‐equation are not fulfilled or if in plasmas with high metal fraction proper data for interaction potentials of neutral metal atoms are unknown.
