Non-Newtonian Fluids and Their Characteristics — Lesson 1

This lesson covers the concept of non-Newtonian fluids, their characteristics, and how they differ from Newtonian fluids. It begins with a recap of Newtonian fluids, explaining their properties and how they behave under different conditions. The lesson then delves into non-Newtonian fluids, discussing their unique characteristics and how they respond to different forces and conditions. It also provides examples of non-Newtonian fluids in everyday life and industry, such as in food processing, cosmetics, and chemical industries. The lesson concludes with a discussion on the classification of non-Newtonian fluids based on their behavior under different shear rates and durations of shearing.
