Pascal's Principle and Eulerian Concept

This lecture covers Pascal's principle, explaining how pressure distributes forces isotropically in all directions, and the Eulerian concept in fluid mechanics, where velocity fields are used to describe fluid movement. The instructor demonstrates how Pascal's principle can be applied to lift heavy items using a hydraulic lift, and introduces the concept of material derivative to analyze acceleration in fluid flow. The lecture concludes with a discussion on conservation laws and the Bernoulli equation in fluid mechanics.
