On the Motion of a Sphere of Oil Through Carbon Dioxide and a Determination of the Coefficient of Viscosity of that Gas by the Oil Drop Method

Abstract

I. Coefficient of Viscosity of C$O_2$ by the Oil-drop Method.—The value of $e$ being known, through work in air, to an accuracy of about.1 per cent., the oil-drop method as developed by Millikan has been used in C${\mathrm{O}}_2$ for the determination of the coefficient of vicsosity of that gas with the result at 23° C. $\eta =\mathrm{I}.490\times {\mathrm{I}0}^{-4\mathrm{}}$.
