A Study of the Measurement of Surface and Interfacial Tension by the Maximum Liquid Drop Volume Method: II. Viscosity Effect on the Tension Measurement

The maximum liquid drop volume (vmax) is measured by using a back-suction micrometer syringe piston technique. Different very viscous liquids are measured by (vmax) and (vf) methods to observe the effect of viscosity on tension measurement. No apparent viscosity effect was observed in surface tensio...

Description
Summary:The maximum liquid drop volume (vmax) is measured by using a back-suction micrometer syringe piston technique. Different very viscous liquids are measured by (vmax) and (vf) methods to observe the effect of viscosity on tension measurement. No apparent viscosity effect was observed in surface tension data obtained by using Harkins–Brown factors and the theoretical correction factors in the viscosity range 5.9–100,900 mP.
