viscosity of water decreases with increase in pressure hert?--68.203.20.238 (talk) 01:12, 9 January 2009 (UTC)--68.203.20.238 (talk) 01:12, 9 January 2009 (UTC)--68.203.20.238 (talk) 01:12, 9 January 2009 (UTC)--68.203.20.238 (talk) 01:12, 9 January 2009 (UTC)[reply]

Why?

Why does viscosity depend on temperature? This is not explained at all - Jeskec (talk) 15:18, 18 January 2009 (UTC)[reply]

There is also an approach by Vogel-Fulcher-Tamann in 1920/1930ish. How are the WLF Parameters C1 and C2 determined? Their values are strongly dependent on the polymer used.

The letter ν (nu)

At the top of the article, it says that the letter ν (nu) will refer to kinematic viscosity in this article (at least unless otherwise noted). In the section on gases, under "Power-Law Force", ν (nu) is used without being defined, but it seems odd for it to be kinematic viscosity the way it is used. Is this ν kinematic viscisity? If not, something needs to be done about this. DubleH (talk) 18:24, 28 March 2021 (UTC)[reply]

It is a dimensionless number in that context. I will fix this when I get the chance, unless someone else is able to first. MaxwellMolecule (talk) 19:33, 28 March 2021 (UTC)[reply]

I have put the definition in Temperature_dependence_of_viscosity#Power-law_force, maybe we should change our notation here to prevent confusion? Alex Bakharev (talk) 01:29, 29 March 2021 (UTC)[reply]
