## Different Types of Pumps Used in the World

Pump is a mechanical device which moves the fluids from one place to another by mechanical action. It may be driven by manual operation, electricity, engines or wind power. They come in various sizes starting from microscopic to large industrial pumps.They mostly operate on the mechanism of reciprocating and rotary. It consumes energy in order …

## Reciprocating Pump – Main Parts, Types, Working, Advantages, Disadvantages with Application

What is Reciprocating Pump? Reciprocating pump is a hydraulic machine which converts the mechanical energy into hydraulic energy. It does this work by sucking liquid into a cylinder containing a reciprocating piston which exerts a thrust force on the liquid and increases its hydraulic energy ( pressure energy of liquid). It is a type of …

## What is Capillarity or Capillary Action?

The rise and fall of a liquid surface in a small thin tube, when it is immersed vertically in a liquid is called capillarity (capillary action). The rise of the liquid surface in the tube is called as capillary rise and the fall of the liquid surface is called as capillary depression. The capillary rise …

## What is Surface Tension?

Surface Tension (ST) is defined as the tensile force acting on the free surface of liquid which is in contact with a gas or on the surface in between two immiscible liquids such that the contact surface behaves like a thin membrane under tension. It is more interesting to know how this tensile force acts …

## What is Cavitation and How it Occurs?

Cavitation is a phenomenon of formation of vapor bubbles of a flowing liquid in a region where the pressure of the liquid becomes equal or less than the vapor pressure. When these vapor bubbles reaches into the region of higher pressure, they collapse and creates high impact pressure. These high impact pressure created by the …

## Centrifugal Pump – Working Principle, Main Parts with Application

Centrifugal pump is a hydraulic machine which converts mechanical energy into hydraulic energy (i.e. pressure energy) by the use of centrifugal force acting on the fluid. The flow of liquid takes place in radial outward direction which is reverse of the inward radial flow reaction turbine. It is used in different areas where fluid is …

## Difference Between Impulse and Reaction Turbine

In this article, we will discuss all the major difference between impulse and reaction turbine. Both types of turbine are used in power plants for the generation of electricity. Instead of their same work of producing electricity, they are differing from each other in much respect. Here we will discuss various differences among them in detail. …

## Types of Wind Turbines – Horizontal Axis and Vertical Axis Wind Turbines

In this article we will learn about different types of wind turbines with their advantages and disadvantages and difference between them. Basically the turbines are used to convert the wind energy into electrical energy with the help of a generator. It extracts the energy from the wind and converts it into mechanical energy and then …

## Pelton Turbine Working, Main Parts, Application with Diagram

In this article we will study about the Pelton wheel or Pelton turbine working, main parts, application with diagram. It is a hydraulic turbine which is used in most of the hydroelectric power plant to generate electricity. It is used for the water available at high head. What is Pelton Turbine? It is a type of …

## What is Viscosity in Fluid Mechanics?

In this article you will learn about what is viscosity, formula of viscosity and unit conversion of viscosity. It is an important property of a fluid which resists the flow of fluid. What is Viscosity? Viscosity is a property of a fluid which offers resistance to flow of one layer of a fluid over another …
