OF the various methods of determining surface tension of liquids, the method of ripples is free from all surface influences. Lord Rayleigh, Dorsey, Grünmach, Kalähne and others have determined the ...

A tensiometer is an instrument used to measure the surface tension (γ) of liquids or surfaces in the domain of physics. Surface tension is the contractive quality of the surface of a liquid that ...

There are some fluids which offer resistance to motion. This resistance of fluid to motion is like internal friction which is similar to friction when solid moves on a surface. This is called ...

(Nanowerk Spotlight) The capillarity-driven uptake of liquids by porous solids can be experienced in daily life, e.g., when a sponge or fabric absorbs water. This spontaneous imbibition or capillary ...

Introduction Have you ever noticed on a rainy day how water forms droplets on a window? Why does it do that instead of spreading out evenly over the whole surface? You might not guess it but this ...

In its most basic form, surface tension is the tendency of liquids to bead up rather than spread out because they are more attracted to themselves (cohesion) than they are attracted to other things, ...

Introduction Have you ever wondered how water droplets form on a window on a rainy day, why some bugs can walk on water or why you use soap to wash your hands? All of these things are related to the ...
