This lesson covers the fundamental concepts of fluid mechanics, focusing on the definition of a fluid, the Eulerian and Lagrangian approaches, and the Reynolds transport theorem. It also delves into the principles of mass and momentum conservation. The lesson explains how fluids are treated as a continuum and how the properties of fluids such as pressure and velocity can be calculated using these principles. It also introduces the Newton's law of viscosity and how it relates to shear stress and shear rate. The lesson concludes with a brief overview of the Navier-Stokes equation, which is a fundamental equation in fluid mechanics.

- A fluid is any material that deforms continuously under the application of a shear stress.
- The Eulerian and Lagrangian approaches are two popular methods to analyze problems in fluid mechanics.
- The Reynolds transport theorem is a general conservation principle that states the rate of change of any system property is equal to the time rate of change of a property within the volume
of interest plus the flux of the property.
- The principles of mass and momentum conservation are fundamental in fluid mechanics and are used to calculate the properties of fluids.
- Newton's law of viscosity relates shear stress to shear rate, providing a relationship for shear stress in terms of velocities.
- The Navier-Stokes equation is a fundamental equation in fluid mechanics that combines acceleration, pressure, viscous, and body force terms.
