[edit] Merge proposal Hagen-Poiseuille flow and Poiseuille's law

I think these articles should be merged. They are about the same thing.

Also, I think it should be "Hagen-Poiseuille flow" (as opposed to "Poiseuille's law")-- I think that is the better name.

  1. Hagen derived it independently.
  2. It is an equation and rarely is valid (read: useful) in real applications; so, not a "law" in my opinion-- c.f. laws of thermodynamics, law of gravity.

  1. Merge Poiseuille's law into Hagen-Poiseuille flow for reasons stated above. Nephron  T|C 11:44, 10 April 2008 (UTC)
Since there was no voiced opinion... I decided to merge, move and re-work.
What was originally here is now in Hagen-Poiseuille flow from the Navier-Stokes equations‎. Going forward it might make sense to split-out the derivation into a separate article and merge what is in Hagen-Poiseuille flow from the Navier-Stokes equations. Nephron  T|C 04:21, 20 April 2008 (UTC)
