POWER-LAW WITH 2 PARAMETERS FOR THE VISCOSITY OF NORMAL AND SUPERCOOLED WATER

Based on an analysis of the temperature dependence of activation energ ies, performed for the rotational diffusion of water molecules and for their reorientation in the proton conductivity process, the relation gamma = 1 + T(s)/T(b) was deduced, where T(s) and T(b) are temperature s of singularity and boiling, respectively, and gamma is the exponent in the power law eta = eta0(T/T(s)-1)-gamma. The modified power law ha s successfully been applied to describe temperature changes in the vis cosity eta of water at normal and higher pressures.
