METHOD OF MEASUREMENT OF SURFACE TENSION COEFFICIENT AND STATIC AND DYNAMIC WETTING ANGLES

摘要

FIELD: chemical, paint-and-varnish and food-processing industries.;SUBSTANCE: proposed method includes pumping liquid through two similar capillaries made in form of circular passages of different length, determination of volumetric flow of this liquid and pressure differential at capillary ends and viscosity and yield point.;EFFECT: enhanced accuracy of measurements; facilitated procedure of determination of viscosity and yield point.;2 dwg
