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 how many inches is 102 centimetersWebJul 5, 2024 · The purpose of this video is to give a guide for UMS ASASI students' in their practical Physics of Sem 1.
