Style

[edit]

Just a quick style note for people editing these "Order of magnitude (XXX)" pages. This is not List of viscosities - we're not trying to collect the viscosity of everything known to mankind here. The idea is to find one or two entries for each order-of-magnitude. The choice of which entries to pick should be driven by familiarity with the average reader. So prefer the viscosity of water over hydrogen peroxide, for example, and resist the temptation to list 50 different common fluids with viscosities clustered around roughly the same value.

Imagine the newspaper reporter who is trying to tell you how big some new building is. He's going to say it's as tall as some number of football fields laid end-to end, or some multiple of the height of the Eiffel tower or something...this table then allows him to look up the measurement of some unfamiliar object - and find something familiar with a similar measurement.

For the more extreme values at the ends of the table, we're into slightly different territory - we need to find extremes of this measurement - so we will be straying into much more obscure phenomena.

Just a note per the ref desk discussion: we should consider flagging ketchup, blood, and perhaps a few others as non-newtonian. I've also had a quick glance at the refs and can't see anything that discusses what the method is for determining "the" viscosity of a thixotropic material.

Corrections

[edit]

I changed the smaller viscosities to scientific notation for better legibility; I did not add or remove any information, such as citations or significant digits. When it said “Steam” on the list, I changed the link from “Steam (software)” (obviously inappropriate) to just “Steam” (gaseous form of water). Okay?--Solomonfromfinland (talk) 19:14, 23 May 2016 (UTC)[reply]

Room pressure?

[edit]

The page mentions "room temperature and pressure", but there is no definition for a standard room pressure. —Eli355 (talk | contribs) 23:38, 5 July 2018 (UTC)[reply]
