Simple Derivation of the Navier-Stokes Equations (Part 2/2)

Tutorial video by Max Ng
This video is about how to derive the Navier-Stokes Equations and how other fluid mechanics equations linked to the Navier-Stokes equations.
This video may not follow a rigorous academic derivation of the concepts shown, but rather prioritises clarity. It is a video by a student for students.

That was a good explanation, thanks! One quibble is that the subscript is missing on the gradient of the compressible part everywhere that the N-S is shown. For instance, d/dx should be d/dx_j on the (2/3 * mu ...) term.

Very nice! Thanks

Glad I found this really helpful. Catched the grand picture but missed the view when it went to the Kronecker delta part. Then, what is the different between (i,j) and k suffix you mentioned?
