Lecture
This lecture introduces the application of electromagnetism concepts to fluid mechanics, focusing on forces, pressure, and buoyancy. The instructor explains the historical experiment demonstrating forces from gas molecules in motion, the concept of pressure as force per unit area, and the variation of pressure in incompressible fluids. The discussion includes the definition of fluids, gases, and liquids, as well as the relationship between pressure, volume, and temperature in gases. The lecture also covers the concept of buoyancy through practical experiments and calculations of pressure gradients in fluids. The instructor emphasizes the importance of understanding these fundamental principles in fluid mechanics.
