[quote name="Meat Engine"]Reynold transport theorem basically gets you F=d(mv)/dt if the change in linear momentum of a control volume is investigated. That is good for looking at the reaction force of a rigid body under the influence of a fluid stream.
The great thing about Navier-Stokes is that a lot of terms drop out for "simple" systems. The most important one is the time rate of change of velocity term. If that doesn't drop out, you get a PDE instead of an ODE, and must proceed with Laplace transforms, similarity methods, or a handful of other equally distasteful methods.
Inviscid flow is another nice assumption. You end up at the Stoke equation.
We finished up with boundary layer theory. I hated it.[/quote]
They teach "Navier–Stokes equations" to the students of 11th grade here in india. I remember i studied it last year, because of the over pressure of bullshit education system. Fuck the teachers and the way they teach
