We carried out statistical calculation of the viscosity 
coefficients of nematic liquid crystals. As the starting point of 
calculation, we used the expression for the tensor of viscous stresses 
obtained within the framework of the relaxational hydrodynamics of 
investigated media constructed on the basis of Zubarev's method of 
nonequilibrium statistical ensembles. The relaxational equation for 
the tensor order parameter was used to calculate the time correlation 
functions that determine kinetic coefficients. The results of theoretical 
calculations were compared with experimental data on the temperature 
dependence for a number of nematogens.
