# Flow Through Pipes

## Head loss in Pipes

In previous posts we have already discussed major losseses in pipes, Hagen Poiseuille & Darcy Weisbach equation to calculate head loss. For minor losses there are direct formulas that need to be remembered Minor Loss 1. Loss due to sudden Enlargement   2. Loss due to sudden Conraction v2 is the velocity in the contracted …

## Laminar and Turbulent Flow

As we have already discussed in earlier topics that whenever a fluid passes over a surface, the surface resists its motion and apply a force to oppose the motion in the similar way when fluid flow a resisting force known as viscous force act. When fluid moves over a surface, each layer of  fluid slides …

## Boundary Layer

Let’s assume a fluid is flowing over a solid body.When a real fluid flows over a solid body, the velocity of fluid at the boundary will be zero. As we move away from boundary in perpendicular direction velocity increases to the free stream velocity i.e. there will be velocity gradient. As we can see in …

## Flow of Viscous Fluid Through Circular Pipe

When fluid flows through pipes there are frictional losses. These losses are due to the resistance due to which some energy of the fluid is lost.  There are two types of energy loss: Minor loss: due to friction Major loss: due to sudden expansion or contraction or bend in the pipe. Major loss It can …
