Navier-Stokes Equations: Hydrodynamics Fundamentals

This lecture covers the fundamentals of hydrodynamics, including the definition, models, and classifications of fluids, the Navier-Stokes equations, conservation of momentum, stresses in fluids, Cauchy stress tensor, hydrostatics, viscous stress tensor, Newtonian fluid model, and the application of the Navier-Stokes equations to incompressible fluids.
