Calculating reynolds number in a pipe

WebThe equation used for the calculation of Reynolds number is: Re = v · D / Vcin Re: Reynolds Number (dimensionless) v: Fluid velocity D: Internal diameter of pipe Vcin: … WebDefinition. The Reynolds number is the ratio of inertial forces to viscous forces within a fluid that is subjected to relative internal movement due to different fluid velocities. A region where these forces change behavior is known as a boundary layer, such as the bounding surface in the interior of a pipe.A similar effect is created by the introduction of a stream …
