Basic Notions of Hydrodynamics
Our goal is to present a very brief introduction to the basics of Hydrodynamics. Namely, we will introduce the notions of ideal fluid, Pascal’s law and the continuity equation. Furthermore, we shall obtain Euler’s equation as an analog of Newton’s second law for the ideal fluid and consider some consequences, such as Bernoulli’s equation, which can be seen as the continuous version of energy conservation. Finally, we will discuss the equation for sound waves, representing a propagating perturbation of density and pressure.
