Capillary Rise
The contact angle between water and glass is acute. Thus the surface of the water in the capillary is concave. This means that there...
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...
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...
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...
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...
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...
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...
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....
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...
