Viscosity–Temperature Correlation for Glycerol–Water Solutions

A four-parameter correlation of the temperature dependence of the viscosity of aqueous glycerol solutions is presented. For large temperature ranges, the errors associated with our correlation are 1–2 orders of magnitude less than those obtained with the exponential and Arrhenius fits and are considerably smaller than the errors due to using the form suggested by Litovitz (1952) for hydrogen-bonded liquids. For pure glycerol, our correlation is slightly better than the five-parameter fit of Stengel et. al. (1982).
