Surface tension

Surface tension is defined as

The process due to which a tight thin sheet is formed on the surface of fluid due to unbalanced molecular attration is known as Surface tension.

For example

  1. Collapse of bubbles.
  2. Mosquito floating on the surface of water .

Units of Absolute viscosity

The SI units of absolute viscosity is Nsec/(m)2.
Poise is also the unit of absolute viscosity Continue Reading »
