Introduction to Mass Continuity — Lesson 1

This lesson covers the concept of flow through porous media, focusing on the basic characterization and parameters of porous media. It delves into the theories of flow through porous media, starting with understanding mass continuity. The lesson explains the continuum assumption, where the porous media is treated as a homogeneous set. It discusses Darcy's law and its application in determining the permeability of the media. The lesson also explains how to measure porosity and permeability, and how these parameters can vary within different sections of the media. The concept of mass continuity in fluid mechanics is also discussed, with a focus on how it applies to porous media.
