## Different Types of Valves

In industries where fluids need to be controlled, valves are used to regulate, direct or control the fluid flow by opening or closing a fluid passage using a gate, ball, or restrictive disc. Depending on the use cases, the valves could be manually, pneumatically, or electrically operated. These valves come in different sizes and shapes, […]

## What are Different Types of Fluid Flow – Complete Explanation

Introduction to Fluid The fluid is a matter that tends to deform continuously under Shear Stress. It consists of both liquid and gases. All the matters on earth can be classified based on their behavior into two categories, i.e., Solid and Fluid. The substance that tends to flow under certain given conditions is called fluid.

## What is Reynolds Number – Definition, Formula, Importance and Application?

Introduction and Significance of Dimensionless Numbers The Analytical and Numerical Analysis in Engineering is difficult to understand with the help of the normal quantities. They don’t interpret any result and can only be used as an Input and Output to a System. The Processing and clear understanding of the system and its behavior is done

## What is Specific Gravity of Water?

Three fourth of our earth is surrounded by water and without water, we cannot survive. All the living things present on the earth utilizes water for their life. But if I ask you what is the specific gravity of water and what do you mean by that then very few of you will be able

## What is Reciprocating Air Compressor?

Reciprocating Air Compressor is a positive displacement air compressor in which air is sucked in a chamber and compressed with the help of a reciprocating piston. It is called as positive displacement compressor because air is first sucked in a chamber and then compression is achieved by decreasing area of the chamber. The area is

## What is Air Compressor and its Types?

Have you ever noticed how we fill the air in the tires of our vehicles? Is there anything that helps to do that? Yes, we have air compressor to compress the air and then this air is used to fill tires of various vehicles. Air compressor has very wide application in various industries. What is

## What is Kaplan Turbine and How It Works?

What is Kaplan Turbine? Kaplan Turbine is an axial flow reaction turbine with adjustable blades. This turbine was developed in the year 1913 by Viktor Kaplan, who was a Austrian Professor. In his design, he combined automatically adjusted propeller blades and automatically adjusted wicket gates to obtain efficiency over a wide range of water flow

## What is Reaction Turbine – Principle, Working, Main Components and Application

Introduction From wind mills to hydro-power plants we have reaction turbines all around the world to generate electricity efficiently. Almost 60% of turbines used in hydro-power plants are reaction turbine. Unlike impulse turbines they remain dipped in water and use the pressure energy of water to generate power. The idea of dipping the whole turbine

## What is Impulse Turbine – Working Principle, Main Parts, Types and Application

Introduction Heard about electricity generation by hydropower plants, know what makes them so efficient that they are lightening up our houses. Yeah that’s the whole effort we have put-in to design our turbines, and make them more and more efficient. Now days an efficient turbine can utilize up-to 90% of the water’s potential energy. Although

## What is Positive Displacement Pump – Definition, Types and Working?

Positive displacement pump (PDP) is a type of pump in which a moving fluid is captured in a cavity and then discharges that fixed amount of fluid. The displacement of fluid takes place by some parts like plunger, piston, diaphragm etc. some of these pumps have expanding cavity at the suction side and a decreasing
