Understanding the properties of fluids is essential to analyze their behavior in working conditions. In this article, we have covered the fluid properties ..
The interplay of the forces of the cohesion and adhesion explains the phenomena of capillarity. When a liquid is in contact with a solid, if the forces of adhesion ..
In this article, we have described briefly the different types of frictional resistances such as dry friction, fluid friction and internal friction encountered ..
In fluid mechanics, the pressure results from a normal compressive force acting on an area. The pressure ‘P’ is defined as force (F) per unit area (A). ..
The pressure in a fluid at rest increases with depth, any body immersed in the fluid will have a greater pressure exerted over its lower surfaces than over its upper ..
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 ..
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 ..
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 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 ..
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 ..
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 (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 ..
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 ..
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 ..
