### Surface Tension

Surface tension is a force per unit length (or surface energy per unit area) acting in the plane of the interface between the liquid...

### Flow of Liquid

Streamline Flow
The flow of liquid in which each of its particle follows the same path as followed by the proceeding particles, is called streamline...

### Hydraulic Machines

The external pressure is applied on any part of a fluid contained in a vessel, it is transmitted undiminished and equally in all directions....

### Stokes’ Law and Terminal velocity

According to Stokes’ law, the backward viscous force acting on a small spherical body of radius r moving with uniform velocity v through fluid...

### Atmospheric Pressure

The pressure of the atmosphere at any point is equal to the weight of a column of air of unit cross sectional area extending...

### Variation of Pressure with Depth

Consider a fluid at rest in a container. In Fig.1 point 1 is at height h above a point 2.The pressures at points 1...

### Viscosity

Viscosity is the property of fluid by virtue of which an internal force of friction comes into play when a fluid is in motion...

### Application of surface tension

A liquid air interface has energy, so for a given volume, the surface with minimum energy is the one with the least area. The...

### Pascal’s Law

Pascal’s Law states that: Pressure in a fluid at rest is same at all points which are at the same height. A change in...

### Bernoulli’s Theorem

If an ideal liquid is flowing in streamlined flow then total energy, i.e., sum of pressure energy, kinetic energy and potential energy per unit...
