Viscosimetric Flow: Understanding Rheology Principles

This lecture covers the principles of rheology, focusing on viscosimetric flow and the reduction of variables complexity. It explains the importance of finding dimensionless numbers and dimensional variates in experimental setups, as well as the drag of objects in fluids. The instructor emphasizes the need to select variables carefully and equate forces to achieve equilibrium. The lecture also delves into coefficient of friction, adimensional variables, and the application of these concepts in practical scenarios.
