Viscous Flow in Capillary — Lesson 3

This lesson covers the concept of flow through porous media, focusing on the calculation of Reynolds number and its application in determining pressure drop. It introduces alternative ways to express pressure drop as a function of flow rate, beyond the commonly used Darcy's law. The lesson further delves into the derivation of equations such as Kozeny Carmen, Blake Pummer, and Ergun equations. It also explains the concept of friction factor and its application in calculating pressure drop in a capillary. The lesson concludes with the introduction of the friction factor chart and its application in turbulent flow.
