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 birchwood casey black brass
Surface tension measurement by Du Noüy ring method
WebThe Du-Nuoy ring method employs a hollow ring with radius 10 mm to measure oil-water interfacial tension (IFT). Assume a perfectly wetting ring was used for the experiment (Figure 1). Figure 1: Du-Nuoy Ring used to measure interfacial tension a. In an experiment involving the measurement of liquid A – water IFT, the total weight measured by ...

WebSep 1, 2024 · There are several ways to measure surface tension such as Du Noüy ring, Wilhelmy plate, and pendant drop. The first two are force-based methods whereas the pendant drop is done with the optical tensiometer. Pendant drop is an optical method Surface and interfacial tension measurements can be performed optically using pendant … dallas stars stanley cup final appearances
