Du no眉y ring method
In surface science, the du Noüy ring method is a technique for measuring the surface tension of a liquid. The method involves slowly lifting a ring, often made of platinum, from the surface of a liquid. The force, F, required to raise the ring from the liquid's surface is measured and related to the liquid's surface tension, γ: See more • Sessile drop technique • Wilhelmy plate See more • Video showing a classical torsion wire du Noüy tensiometer • Picture of a classical torsion wire du Noüy tensiometer (National Institutes of Health) See more 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.
