Talk:Steady flow

What this page currently desribes is Laminar flow. Steady flow simply means average quantities dont change with time. So turbulent flows can often be desribed as steady (or maybe you'd prefer 'statistically-steady'). At least according to me. Dougalc 22:18, 7 May 2006 (UTC)

just a question
What the article says is that the steady flow is the flow at which the velocity at a point will remain constant w.r.t time. And you said that the flow will be steady for Rє < 1000.

My question is, what if the flow rate is changing while Rє is still <1000 ( just like what happens when we are evacuating a tank and considering the flow velocity at the exit point. ) ?

will we call it steady flow ? —Preceding unsigned comment added by 196.202.96.69 (talk) 07:26, 8 September 2007 (UTC)

suggestion and answer to question
I learned to call what is defined here as 'Steady Flow' instead 'Laminar Flow' and I would recommend merging this content with the article on Laminar flow.

To answer the question, the flow speed can change without turbulence, so you would still call flow with a Reynolds number less than 1000 laminar (or steady, streamline) flow. The statement in this definition regaring 'Eulerian velocity' doesn't say that it is constant, only that the operator is not chaotic. I hope this makes sense.
