Lecture
This lecture covers the discussion on hydrostatics and forces on submerged surfaces, including an exercise to calculate forces on a tank sidewall and a detailed explanation of the Archimedes principle. The instructor explains how to calculate vertical and horizontal forces on submerged surfaces, emphasizing the importance of pressure distribution and the weight of the displaced volume. The lecture also delves into the concept of streamlines in fluid dynamics, steady flows, and Newton's second law for fluid elements, highlighting the neglect of viscous forces in the analysis. The instructor concludes by introducing the Bernoulli equation and discussing the significance of streamlines in describing fluid flow.
