Talk:Actual cubic feet per minute

Free air

Descriptions of compressors often state x cubic feet per minute of "free air". Does "free air" mean Actual cubic foot per minute? Biscuittin (talk) 16:03, 15 October 2008 (UTC)

Move

I moved this article from "actual cubic foot per minute" to "actual cubic feet per minute". While the singular form is usually preferred for article titles, I thought that this was not the case for this particular article. First, the plural appears to be more commonly used, one of the most important considerations in choosing an article name. Second, in my opinion, the singular is somewhat awkward. Third, related articles also use "feet" instead of "foot". Example articles include, "cubic feet per minute", "standard cubic feet per minute" and "million standard cubic feet per day". -- Kjkolb (talk) 05:51, 11 December 2009 (UTC)

this should be a sub article to volume flow

the statements made in this article do not provide a neutral point of view and is the result of salesmanship and marketing. it attempts to create an prejudicial preference where none should exit. its inaccuracies are only evident when all volume flow specifications are discussed together.

Where did this definition come from: Actual cubic feet per minute is the volume of gas flowing anywhere in a system independent of its density. This does not match ACGIH that indicates that acfm is the cubic feet per minute at the actual density of the air, which requires correction for moisture, temperature, duct static pressure and elevation. The definition provided leads one to think that the measured velocity times the area of the air flow is acfm. I don't believe that is really the case. — Preceding unsigned comment added by 192.100.51.131 (talk) 15:47, 31 August 2015 (UTC)

CFM

Too bad there is no Cubic Feet per Minute (CFM) article, even though there is a whole article on ACFM. Unfortunately, this ACFM article claims to be the more standard unit, whereas on planet Earth it is CFM that is the standard unit and is used probably over a hundred times to describe product capabilities for 1 time that ACFM is used! A casual reader trying to find out what CFM means a product would be redirected here and misled into believing that their product was somehow misleading them with an "unqualified" CFM number. But the number is not normally qualified.MacroMyco (talk) 18:17, 20 May 2017 (UTC)
