Is there an English word for "Firewater well" (literally) found in Finnish and German Wikipedia?
Fire hydrant is a a connection point by which firefighters can tap into a water supply. These are usually pressurized but in Finland we have historic things called fi:Palokaivo which is just a groundwater well intended for firefighters to be used with a pump. A literal translation is "fire well", a well for firefighting. In German there is also word for that: de:Löschwasserbrunnen, literally "firewater well". The reason I'm asking this is to fill in an English description for an image describing a Finnish symbol for a firewater well, found in Commons. Now I just put there that it is a "firewater well". --Vesa Linja-aho (talk) 17:48, 9 April 2020 (UTC)
 * Our article on standpipes describes the systems found in buildings for that purpose, and it's broadly applicable outside too. Standpipes may or may not be inherently pressurized. Out in the country in North America you may see so-called "dry standpipes" or "dry hydrants" that are simple lengths of pipe with a hose fitting, extending into a water source such as a pond or watercourse. There's no exact English equivalent term that I'm aware of. See also dry riser, which is a more common term in the UK. Dry hydrant design here     Acroterion   (talk)   18:07, 9 April 2020 (UTC)


 * In America, at least, the term "firewater" is a synonym for Moonshine. ←Baseball Bugs What's up, Doc? carrots→ 18:22, 9 April 2020 (UTC)
 * The term "firewater" can also mean "water for extinguishing fires", also in the US, as seen here. It is mainly used in the context of industrial plants, in which the firewater system is an integral part of the design. For firewater wells, the term "fire well" is occasionally used (see e.g. here). However, you should not assume that readers will understand this term without explanation. --Lambiam 20:27, 9 April 2020 (UTC)
 * In the UK, firewater (fire fighting) seems to refer to runoff of used water which may be polluted, although I've never heard of it until just now. British fire engines carry pumps that can lift water from ponds or streams, but a Google search hasn't found any reference to using wells, which are not a common thing here anyway. I think "well for firefighting" might be clearer. Alansplodge (talk) 22:49, 9 April 2020 (UTC)
 * The term doesn't seem to be use for the contaminated water in NZ much that I can tell, at least not among the general media. I say this because I cannot find any references to the term in relation to the New Zealand International Convention Centre fire, where the contaminated water was discussed quite a bit. The only sources I found are [//www.nzherald.co.nz/nz/news/article.cfm?c_id=1&objectid=12281541] which is just the headline and also is using it in a different way (it's the water from the SkyCity fire) and [//auckland.scoop.co.nz/2019/10/fire-water-discharge-amazing-double-standard/] which is just a press release and also is I suspect is mostly using it in the other headline way just without mentioning which particular fire because it's understood.

 * Thank you very much for your replies. I changed the description now "An old sign for a well for firefighting water in Finland". --Vesa Linja-aho (talk) 17:54, 13 April 2020 (UTC)

First coronavirus: 1918-
When did the 1918 coronavirus happen and when and how did it end? 86.134.123.138 (talk) 19:42, 9 April 2020 (UTC)
 * If you're referring to the 1918 pandemic, it was caused by an influenza virus (specifically, Influenza A virus subtype H1N1), whereas (human) coronaviruses were discovered in the 1960s. 107.15.157.44 (talk) 20:01, 9 April 2020 (UTC) . . .

Child's height to adult's height

And what age do they stop growing taller? 18 or 20? 86.134.123.138 (talk) 21:44, 9 April 2020 (UTC)


 * Different people grow at different rates. There are so many variables (genetics, diet etc etc) in this that it will be hard to get a definitive answer. MarnetteD&#124;Talk 21:52, 9 April 2020 (UTC)

I've just calculated Mary-Kate Olsen's height from age 18 to 8 by 6.3 cm with a calculator, the height site etoolsage and a chart in Microsofts Word & Powerpoint and it seems she might've been 37 inches (94 cm) taller, 38.6 inches (98 cm) smaller than Bob Saget. And when Bob kneels down to Mary-Kate, he's about (divided by 2) 37.8 inches (96 cm). Have a look at those two images 1 & 2. 86.134.123.138 (talk) 20:37, 10 April 2020 (UTC)
