8. Basics of Fluid Mechanics – II

The chapter covers the fundamentals of fluid mechanics, focusing on fluid kinematics and velocity fields, specifically exploring the concepts of Eulerian and Lagrangian descriptions of flow. It discusses dimensional flow analysis, distinguishing between steady and unsteady flows, as well as one-dimensional, two-dimensional, and three-dimensional flows. Important properties such as velocity, pressure, and density are treated within the framework of field representation.
