Discussion Overview
The discussion revolves around introducing fluid dynamics concepts, particularly focusing on Bernoulli's principle and the transition to more complex equations like the Navier-Stokes equations. Participants explore the implications of viscosity in fluid flow and suggest various starting points for understanding these concepts.
Discussion Character
- Exploratory
- Technical explanation
- Conceptual clarification
Main Points Raised
- One participant requests a gentle introduction to fluid dynamics.
- Another participant provides a link to Bernoulli's principle as a foundational concept.
- Some participants note that Bernoulli's principle applies under the assumption of inviscid flow, while acknowledging that viscosity complicates the analysis, necessitating the use of Navier-Stokes equations.
- There is a suggestion to explore boundary layer analysis as an application of viscous flow concepts.
- One participant expresses concern that directing beginners to boundary layers may be overwhelming and proposes starting with Plane Couette flow instead.
- A later reply humorously questions the fear associated with boundary layers while agreeing with the suggestion for a gradual approach.
Areas of Agreement / Disagreement
Participants generally agree on the need for a gradual introduction to fluid dynamics concepts, but there is a divergence in opinions regarding the appropriateness of starting with boundary layers versus simpler topics like Plane Couette flow.
Contextual Notes
There are limitations in the discussion regarding the assumptions made about the audience's prior knowledge and the complexity of the topics introduced. The discussion does not resolve how best to introduce fluid dynamics to beginners.

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!
