The maximum liquid drop volume (v(max)) is measured by using a back-suction micrometer syringe piston technique. Different very viscous liquids are measured by (v(max)) and (v(f)) methods to observe the effect of viscosity on tension measurement. No apparent viscosity effect was observed in surface
Described herein is a two-phase nonempirical method for the determination of surface or interfacial tension of stationary systems that also allows the determination of drop correction factor. The method is based on the theoretical calculation of the drop profile associated with the maximum volume of
