Studies in Newtonian Flow. V. Further Verification of the Free‐Space Viscosity Equation

Values of the limiting specific volume v0 calculated by a trial‐and‐error procedure from n‐alkane viscosity data using the author's free‐space viscosity equation, lnη=B(v0/vf)+lnA, agree substantially with previously published values obtained by extrapolation of density data. Values of v0 for mercury, sodium, benzene, carbon tetrachloride, dichlorodifluoromethane, and water were calculated by the same trial‐and‐error procedure. In all cases the free‐space equation gave a much better fit than the corresponding Andrade temperature equation, lnη=B/T+lnA.
