This lesson covers the transport phenomenon of non-Newtonian fluids, focusing on time-independent fluids flow through pipes. It delves into the different aspects of non-Newtonian behavior, the measurement of rheology, and the derivation of conservation equations of mass and momentum. The lesson further explores the application of these principles to understand the transport phenomena of different types of non-Newtonian fluids, such as power law fluids, Bingham plastic fluids, and Herschel Bulkley fluids. It also discusses the impact of different geometries on the flow of these fluids. The lesson concludes with an illustrative example of how the pressure drop and flow rate of a shear thinning fluid differ from that of a Newtonian fluid.
