Abstract

An equation is presented which represents the variation of viscosity of a liquid with pressure in terms of the compressibility (ßT), thermal expansion (a) and molar volume (V) of the liquid (?In ?/?P)T = ßT+(Va/2.45R) The derivation of the equation from an equation developed by Eyring and coworkers is given and the application of the equation is shown to 17 liquids for which data are available.
