ARTICLE NO. CS974891 NOTE Effect of Neck Formation on the Measurement of Dynamic Interfacial Tension in a Drop Volume Tensiometer so that hydrodynamic effects can be neglected. Conditions under which neck formation may occur are studied, and a model is proposed to relate Dynamic interfacial tension
A novel, fast formed drop technique is developed for measuring dynamic surface and interfacial tension of surfactant solutions. It employs the basis of the capillary pressure methods. A new way of formation of a fresh interface is the key point in the proposed technique. It is based on the fact that
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
The maximum liquid drop volume (nu(max)) is measured using a back-suction technique with a micrometer syringe piston. The residual amount of liquid on the tip was determined and the tension data calculated from the theoretical correction factors are well in accordance with those from the falling dro
