## One, Two and Three Dimension Flow

One dimensional flow is the type of flow in which the flow characteristics such as velocity, pressure, density, temperature etc. are the function of time and one space co-ordinate only. Mathematically, u=f(x) ; v=0 ; w=0…...

## Pressure Measurement by Pressure Gauges

Most of the conventional pressure gauges are of a mechanical type. These gauges embody on elastic element which deflects under the action of the applied pressure. This movement mechanically magnified and read with the help of...

## Pressure Measurement By Manometers

Manometers is the device which is used for measuring the pressure at a point in a fluid by balancing the column of fluid by the same or another column of liquid. Simple Manometers Simple manometers are used to measure the...

## Surface Tension | Definition and Examples

The surface tension is due to cohesion between particles at the free surface. Due to molecular attraction, liquids have properties of cohesion and adhesion. Cohesion is due to the force of attraction between molecules of same...

## Basic Concepts of Fluid Mechanics and Flow of Fluids

Fluid may be defined as a substance which is capable of flowing. It has no definite shape of its own but it confirms the shape of the containing vessel. A small amount of shear force exerted on a fluid will cause it to undergo a...

## Basic Thermodynamics of Refrigerators and Heat Pumps

The ideal body having large thermal energy capacity which either continuously supplies or absorbs the infinite amount of heat without changing its temperature is called thermal energy reservoir or heat reservoir. If the reservoir...

## Statements of Second Law of Thermodynamics

The second law of thermodynamics is stated in two ways. Kelvin Planck statement and Clausius statement. Kelvin Planck Statement The Kelvin Planck statement can be expressed as “It is impossible for any device that...

Consider an open system through in which the working substance flows as a steady rate as shown in figure. The working substance entering the system at (1) and leaving the system at (2). Let, p1 be the pressure of the working...
