## Capillarity

The interplay of the forces of the cohesion and adhesion explains the phenomena of capillarity. When a liquid is in contact with a solid, if the forces of adhesion ..

## Pressure Scales

In fluid mechanics, the pressure results from a normal compressive force acting on an area. The pressure ‘P’ is defined as force (F) per unit area (A). ..

## Types of Fluid Flow in Pipes: Laminar, Turbulent, Transient

Pipes are circular in cross section area, identical to the shape of a roll of paper towels. We generally use pipes in our homes to supply water from water tank to kitchen, ..

## Pascal’s Law

Pascal’s law states that A small force (F1) is applied to piston with a small area (A1) produces a much large force F2 on the larger piston. It is schematically ..
