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 ...

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 ...
