## Centrifugal Pumps – Classification and Components

Centrifugal pumps are the devices which convert the mechanical energy into hydraulic energy by means of centrifugal force acting on the fluid. Centrifugal pumps are classified as roto dynamic type of pumps in which a dynamic...

## Working of a Double Acting Reciprocating Pump

In a double acting reciprocating pump, the suction and delivery strokes occur simultaneously. When the crank rotates from IDC to ODC, a vacuum is created on the left side of the piston and the liquid is sucked from the sump...

## Working of a Single Acting Reciprocating Pump

In a single acting reciprocating pumps, liquid acts on one side of the piston only. Image shows a single acting reciprocating pump which has one suction pipe and one delivery pipe. It is usually placed above the liquid level in...

## Reciprocating Pumps – Classification

The reciprocating pumps is a positive displacement pump. It operates on the principle of actual displacement or pushing the liquid by a piston or plunger that reciprocates in a closely fitting cylinder. These pumps usually have...

## Methods of Dimensional Analysis – theteche.com

There are two methods of dimensional analysis used. Rayleigh’s method Buckingham π-Theorem Rayleigh’s Method In Rayleigh’s method, the expression is determined for a variable depending upon maximum three or...

## 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...
