Bingham Plastic Fluids Flow through Pipes — Lesson 3

This lesson covers the transport phenomena of non-Newtonian fluids, specifically focusing on Bingham Plastic Fluids flowing through pipes. It delves into the velocity profile, volumetric flow rate expressions, and friction factor equations for different types of generalized Newtonian fluids. The lesson also discusses the equations for velocity profile and volumetric flow rate when the fluid is of power law type and Ellis model fluid. It further explains the concept of viscoplastic fluids and how their velocity profile changes when flowing through a pipe. The lesson concludes with a detailed example problem that illustrates the application of these concepts in real-world scenarios.
