In the mathematical development of the theory it is first necessary to define the coefficient of viscosity.

Among them are such as: total internal energy, kinetic and potential energies, heat-capacity and thermal conductivity, surface tension, vapor pressure, viscosity, coefficient of self-diffusion, osmotic pressure, solvent activity, etc.
Hierarchic Models of Turbulence, Superfluidity and Superconductivity
Applying the consequence of the crossover to the entangled linear and star branched polyethylene and hydrogenated polybutadiene, we had explained simultaneously the molecular weight dependence and the Arrhenius activation energy of the viscosity and diffusion coefficient [13,15,16].
