The paper features theoretical model of computing (based on methods of statistical thermodynamics and kinetic theories of gas) viscosity and thermal conductivity in the liquid and gas domain for pure components. To calculate the viscosity of real fluid, the models developed on the basis of Lennard-Jones intermolecular potential are applied. Heat capacities are calculated by use of statistical thermodynamics. The paper features all important contributions (translation, rotation, internal rotation, vibration, intermolecular potential energy and influence of electron and nuclei excitation). The analytical results obtained by statistical thermodynamics are compared with the REFPROP model and show relatively good agreement.
