Reynolds Number given Darcy Friction Factor Formula

Fx Copy

LaTeX Copy

The Reynolds number is the ratio of inertial forces to viscous forces within a fluid which 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. Check FAQs
