Fluid Dynamics: Pressure and Viscosity

This lecture covers the fundamentals of fluid dynamics, focusing on pressure and viscosity. The instructor explains the concept of pressure at a point, the balance of forces, and the behavior of fluids at rest. The lecture also delves into the topic of viscosity, discussing Newtonian fluids and the relationship between shear stress and velocity gradients. Various examples are provided to illustrate the application of these concepts in solving flow problems.
