## Viscosity of a Fluid

A fluid at rest cannot resist shearing forces and if such forces act on a fluid in contact with a solid boundary as shown in below figure, the fluid will ..

## Types of Fluid Flow in Pipes: Laminar, Turbulent, Transient

Pipes are circular in cross section area, identical to the shape of a roll of paper towels. We generally use pipes in our homes to supply water from water tank to kitchen, ..

## Gas Laws

Gas Laws explain the behavior of an ideal gas in terms of temperature, pressure, volume. The following are the some of the important gas laws: Boyle’s Law Charles ..

## Friction Factor and Darcy-Weisbach Equation

In fluid dynamics, the pipe flow equation most commonly used is the Darcy-Weisbach equation that prescribes the head loss hf to be: Where ‘L’ is the pipe ..

## Types of Fluids

Fluids are defined as substance that flow or deform under the applied shear stress. Fluid has no definite shape of its own. It assumes the shape of its container. ..

## Reynolds Number

Reynolds number (Re) is an experimental number used to predict the flow velocity in fluid flow at which turbulence will occur. It is a non-dimensional velocity ..

## Losses in Pipe Fittings and Valves

In addition to losses due to friction in a pipeline system, there are also losses associated with flow through valves and fittings. These losses are called minor ..

## Properties of Fluids

Understanding the properties of fluids is essential to analyse their behavior in working conditions. In this post we have written the fluid properties namely ..

## Pascal’s Law

Pascal’s law states that A small force (F1) is applied to piston with a small area (A1) produces a much large force F2 on the larger piston. It is schematically ..

## Cavitation

Under certain conditions, areas of low pressure can occur sometimes locally in a flowing fluid (liquid or gas). If the pressure in such areas falls below the vapour ..

## Notes on Pressure

Pressure (symbol: p or P) is a measure of force distribution over any surface associated with the force. Pressure is a surface phenomenon and it can be physically ..

## Types of Frictional Resistance

In this article we will briefly discuss the types of frictional resistance such as dry friction, fluid friction and internal friction encountered in mechanics. ..

## Bernoulli’s Principle and Equation

During 17th century, Daniel Bernoulli investigated the forces present in a moving fluid, derived an equation and named it as an Bernoulli’s equation. Below ..

## Manometer Types

A manometer is a device used for measure the pressure of a fluid by balancing it with against a column of a liquid. Five different types of manometers are shown ..
