This lesson covers the fundamental aspects of flow through porous media, focusing on the definition of porous medium, its characteristic parameters, and its applications. It delves into the concept of Darcy's law, explaining the relationship between pressure gradient and velocity in the context of fluid flow. The lesson also discusses the different types of pores (macro, meso, and micro) and their impact on the flow mechanism. It further explains the concept of permeability, its unit (Darcy), and its relation to flow rate, viscosity, and pressure gradient. The lesson concludes by highlighting the importance of understanding these concepts for various applications, such as oil recovery and sequestration of chemicals.
