An example of a fluid with low compressibility

Click For Summary

Discussion Overview

The discussion revolves around identifying a fluid with low compressibility, exploring the definitions and thresholds of what constitutes "low compressibility." Participants consider specific fluids and their properties in relation to this concept.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant asks for examples of fluids with low compressibility.
  • Another participant suggests water as a candidate, noting its near-incompressibility.
  • A third participant expresses concern over the tone of the previous response, indicating a misunderstanding.
  • Further clarification is provided that "low compressibility" can vary in interpretation, potentially ranging from zero to somewhat compressible fluids.
  • The original poster acknowledges the misunderstanding and confirms that water meets their needs for modeling purposes, both as an incompressible fluid and as a compressible fluid with modifications.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the precise definition of "low compressibility," indicating that multiple interpretations exist. However, there is agreement that water is suitable for the original poster's requirements.

Contextual Notes

The discussion highlights the ambiguity in defining "low compressibility" and the potential for varying interpretations based on context.

Hi,

Does anyone know a fluid with low compressibility?

Thanks,

H

How low are you thinking? How about, say, water, which is so incompressible that it can pretty much always be treated as such.
 
You're right... wasn't thinking at all!
But no need to be rude! When you help people be nice about it!
 
I don't think boneh3ad was trying to be rude. It was a genuine question on how low your idea (or requirement) of low compressibility is. Low compressibility could mean zero, or it could have been something fairly compressible, but not very much (which would exclude water).
 
Oooh! In that case I'm really sorry for the misunderstanding!

I think water is Ok for my case. As I was looking for a fluid that could be modeled as incompressible and also as a compressible fluid with modification to the incompressible fluid code, if needed.

Thanks very much!
