Lecture
This lecture covers the energy argument and mechanical analogy in fluid dynamics, explaining the determination of forces on objects and the continuity equation. It delves into the non-linear balance of momentum, the adiabaticity index, and the equation of state for perfect fluids. The instructor discusses the implications of incompressible fluids, the system of equations, and the conditions for fluid elements. The lecture concludes with examples illustrating the application of the concepts discussed.
