Surface tension formula for dunoy ring
The surface tension and correction factors are expressed by the following equations: γ = F 4 π R f {\displaystyle \gamma ={\frac {F}{4\pi R}}f} where γ is surface tension, R is the average diameter of the ring, and f is correction factor. See more 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.

WebThe du Noüy–Padday method is a minimized version of the du Noüy ring method replacing the large platinum ring with a thin rod that is used to measure equilibrium surface tension or dynamic surface tension at an air–liquid interface. In this method, the rod is oriented perpendicular to the interface, and the force exerted on it is measured. WebDunoy's ring is a common method used to measure surface tension. The ring is place in the surface of the liquid allowing the liquid to adhere to the ring. The force required to pull the …
