Fluid Mechanics: Hydrodynamics and Surface Tension

This lecture covers the principles of fluid mechanics, focusing on hydrodynamics and surface tension. Topics include laminar and turbulent flow, Bernoulli's equation, viscosity, Poiseuille's law, Reynolds number, tension in liquids, Laplace's law, and contact angle. The instructor explains the behavior of fluids in different scenarios, such as flow between plates, in cylindrical tubes, and the formation of drops. Practical applications like blood flow, capillarity, and bubble formation are also discussed.
