Wait isn't this just some fluid physics equation?

Like, incompressible fluid flow, iirc.

It looks like it given the symbols used. P for pressure, rho for density etc. u-arrow is definitely a vector field, so it could be fluid flow. Otherwise it could be equally anything described by a vector field, like electromagnetism or gravity but they usually have a lot more E and G involved I think. I used to solve these but then I got a certificate so now I don't have to.

It's a fluid dynamics equation, cannot be analytically solved unless laminar flow assumption is valid.

It really reminds me of all those static and velocity pressure calculations I had to do in undergrad, until I got the degree.

u stands for velocity.

Yeah i mean, now you know what to search for on the internet.

Them funny hieroglyphics ain’t nowhere on MY keyboard.

Dunno what kinda crazy com’nist Martian setup y’all are runnin’.

Naviers stokes equation looks incompressibility fluid. Only possible to solve it for strictly laminar flow.
