Carnegie Institution of Washington publication. 152 CONDUCTIVITY AND VISCOSITY IN MIXED SOLVENTS. kinetic energy possessed by it; t is the time of flow through the capillary tube of radius r and length I; v is the volume of fluid flowing in time t. The viscosity of fluids is, however, most commonly found by the method recommended by We find by this method the time of flow of a fixed volume through a capillary tube, under the pressure due to the differ- ence in level of the free surfaces of the fluid. The viscosity is found from the ratio of the time of flow for the fluid in question to the time of flow for an equal volume of water, multiplied by the specific gravity of the solution. This is expressed by the formula „ iot in which r;0 is the coefficient of viscosity for water, S0 its specific gravity, and. 10- 75 ;J 100-6 Percentage of Acetone FIG. 71. — CONDUCTIVITY OF COBALT CHLORIDE IN MIX- TURES OF ACETONE AND METHYL ALCOHOL AT 25°. t0 its time of flow, at a given temperature.
