Correlating viscosity with temperature and other properties

Simple viscosity equations based on linearities 1/η^e (or φ^e) vs. T; T/η^e vs. T and φ^e vs. P; (η, viscosity; φ, fluidity; T, temperature; and P, any property or property function linear with T, such as, density, refractivity, and surface tension)] are given for glycerol, triglycerides, glyceride oils, n-fatty acids, esters, an alcohol, and an amine.
