They are removed by moving to more complicated equations such as Navier-Stokes.

Hehe, I liked your response.

To the OP, what boneh3ad is saying is that the main constraint for bernoulli is the flow is inviscid. To account for viscosity things get more complicated such as using N/S equations to deal with what occurs in viscous flows. For an application of this, look for topics related to boundary layer analysis to get a sample.

You are going to scare the kid by direction him straight to boundary layers. Baby steps. Plane Couette flow may be a nice starting point.

Baaah, what's so scary about boundary layers??? *cough* *cough*

Good point however!
