Ideal-Gas Equation and Absolute Temperature

Ideal-Gas Equation & Absolute Temperature

Ideal-Gas Equation The ideal gas equation connecting pressure (P), volume (V) and absolute temperature (T) is PV = μ R T since PV = constant and...
Heat and Temperature

Heat And Temperature

The branch dealing with measurement of temperature is called thermometry and the devices used to measure temperature is called thermometers. Heat Heat is a form of...
Capillary Rise

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

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

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

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

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

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

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

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....
