Abstract
In this paper it is shown that the viscosity of the liquid normal paraffins can be accurately defined as a simple function of relative free-space except for values in the neighborhood of the freezing points of each compound. A novel method of extrapolating the specific volumes of this family of compounds to absolute zero is described which permits the calculation of reliable values of the relative free-space from density data. An expression of the same form as the author's function, but in which temperature rather than free-space is the primary variable (the so-called Andrade equation), fails to reproduce the viscosity of n-heptadecane over the same range of temperatures within the limits of the known accuracy of the measurements.
