Turbulent Flow: Turbulent flow is defined as that type of flow in which the fluid particles move in zigzag way. The fluid particle crosses the paths of each other. The Reynolds number (Re) is greater than 4000 then the flow is said to be turbulent. For example: a. Flow in river at the time of … Read more

Flow Through Pipes

by

Introduction to pipe flow: A pipe is a closed conduit (channel) which is used for carrying fluids under pressure. Pipes are commonly circular in section. The fluid in the pipes are subjected to frictional resistance due to shear stress. Reynolds experiment and flow based on Reynolds number.  Reynolds experiment is used to display laminar, transion … Read more
