surface tension formula ring

pull a ring out of water - Physics Forums.
SCHEIBEL EQUATION FOR DIFFUSION IN LIQUIDS .. The surface tension, γ, may be defined as the force/unit length parallel to the surface which ... The static Wilhelmy plate method is tions must be avoided and the ring must be accurately.
Among the various ways to determine surface tension, Du Noüy ring method. The surface tension can be determined using the Young–Laplace equation in the.
Ring Method. In this method liquids with a known surface tension are used and a plate made of the material to be investigated is used instead of. The wetted length of the plate must be measured; it is obtained from the following equation:.
Cleanliness of the ring and vessel are both paramount to accurate test results.. Record the exact temperature of the liquid; surface tension is inversely related to . Charts, formulas, and computer programs can be used to obtain the.
it can be seen that a second equation is required which also describes the surface energy of the solid as a function of the interfacial tension solid/liquid and the.
