Du nuoy ring method
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.

WebJul 12, 2024 · Ring Detachment Method (du Nouy tensiometer): The du Nouy’s ring method is similar to the Wilhelmy plate method, but it uses a ring or loop of wire. A platinum or Iridium wire of ~4 cm in circumference is suspended from the loop attached to a scale through a torsion wire. WebJan 1, 2009 · Equation (2.7) shows the relationship for the calculation of surface tension by the du Nouy ring method. In this equation, P T is the total force on the ring which is measured, P R is the weight of the ring, R is the radius of the ring, and γ ideal is the ideal surface tension. In practice, a meniscus correction factor is required because the ...

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. 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
WebThe Du Nouy ring method is used to measure static surface and interfacial tensions of liquids (Hiemenz 1986, Couper 1993). The apparatus required to carry out this type of measurement consists of a vessel containing the liquid (s) to be analyzed and a ring which is attached to a sensitive force-measuring device (Figure 5.13).
