Untitled[edit]

Needs to include a nicer simple sentence giving a water wapour % in air (absolute). Room temp., etc.

Simplify Relative Humidity?[edit]

At the moment, the article says this about relative humidity, which is ambiguous - "how much water vapour the air could potentially contain at a given temperature". The words 'could potentially contain' is not clear in its meaning. For example - does it actually mean maximum amount of water vapour, or some average amount of water vapour, or a minimum amount? Currently, just writing 'potentially' can mean anything. KorgBoy (talk) 23:07, 30 July 2021 (UTC)[reply]

@KorgBoy: I'm not so sure it's an issue. I have a 20 litre bucket. How much water could that bucket potentially contain? That said, if you can come up with clearer wording, have at it! Edit away, or make a suggestion. Worst that can happen if you choose to edit in good faith is that it will get reverted. WP:BRD etc. Chumpih ^t 15:06, 19 January 2022 (UTC)[reply]

@Chumpih: - for clarity, the wording could be 'What is the maximum amount of water that the bucket could potentially contain?'. When we just say 'how much water could the bucket potentially contain?', then the word 'potentially' could be considered to mean 'possibly', so that anybody could say that the bucket could 'possibly' (ie. potentially) contain 1 millitre, or even 1 litre, or 15.74 litre, or any amount in the range zero to twenty litre. KorgBoy (talk) 07:38, 9 August 2022 (UTC)[reply]

@KorgBoy I agree it's not adequately worded. For a start, there's such a thing as supersaturation, where the air contains more water vapour than "ought" to be possible but the water doesn't condense out because there's nothing for it to condense on. So the RH can potentially be over 100% . . . !

As I understand it, 100% RH is the point above which the mixture can't be in equilibrium and water will condense out, but I'm not sure of the precise definition. Musiconeologist (talk) 03:01, 30 March 2024 (UTC)[reply]

what is the maximum absolute humidity?[edit]

If the rel. humidity is near 100%, at which temperature does the abs. humidity reach its maximum? Or is there no limit? The formula tells me that at 500°C a abs. humidity of 248068 g/m³ can be reached. But I guess this will not be possible. --JMS (talk) 22:11, 18 January 2022 (UTC)[reply]

Absolute Humidity has Incorrect Units[edit]

What I think should be changed: Under the Absolute Humidity section, in the penultimate sentence, the commonly used units in SI are actually g/m³ and kg/m³, NOT g/kg and kg/kg. Also, the last sentence was perhaps meant to say that any units of mass and volume can be used (lbs/ft³ are often used in the US).
Why it should be changed: Measurements for absolute humidity are recorded in units mass per unit volume.
References supporting the possible change (format using the "cite" button): The equation provided in the Absolute Humidity section itself gives absolute humidity as a ratio of mass of water vapor in air to the volume of air at a given temperature. You can also consult the Engineering ToolBox website, namely this page: https://www.engineeringtoolbox.com/amp/absolute-humidity-air-d_681.html

oz/cubic yard is madness[edit]

Why does the table of absolute humidity values a useless extra set of values in oz/cu. yd? The table is overfull with these useless extra numbers included. If there's some tiny subset of people who actually use these they'll be peculiar engineers or similar from the USA, a staggering minority of possible users of this page. Take these out for clarity. Ecwiebe (talk) 22:17, 8 January 2024 (UTC)[reply]

delete the numbers in brackets, but perhaps keep the Farenheit temperatures. The os/cubic yard doesn't help with clarity. Even if there were arguments to retain, it may make more sense to have them in a separate table. Chumpih ^t 06:49, 5 March 2024 (UTC)[reply]
