WebTo measure the surface tension between a liquid and the air, the duNouy ring is placed below the surface of the liquid. This test is performed by pulling the ring upward through the surface of the liquid. The force needed for the ring to break the surface (overcome the surface tension) is determined. This measurement is in dynes/centimeter. WebThe ring method has three main issues, which make it a less than good option for measuring exacting surface tensions, particularly on surfactant based solutions, wherein the rate of surfactant diffusion to new formed surfaces is particularly slow, as is the case particularly for large molecule surfactants, amphoterics, and fluorosurfactants. 1. in a kite are opposite angles equalWebThe force is measured on a ring shortly before a liquid film tears using a torsion meter.
