Volume changes based on temperature and pressure. So when we reference volume measurements like for flow rates, we typically do the math to adjust those to standard temperature and pressure. Standard pressure is 1 atm but standard temperature varies based on who you’re talking to because of competing standards. It’s usually 25 C or 20 C.
When we want to reference the non temperature and pressure corrected volume, we append actual to it so that people know what the measurement is. Some people don’t do that and that causes confusion for others using their work if the reading is standard or actual.
Maybe a weird aside, but what does this mean?
Are there “liters” other than the 10cm x 10cm x 10cm definition?
To totally confuse you: The USA uses the “standard litre” while Europe uses “normal litre”:
https://en.wikipedia.org/wiki/Standard_litre_per_minute
You mean the flow rate of a volume of liquid? What are you confused about exactly?
They’re asking why it’s “standard litres per minute”, instead of just “litres per minute”
Oh, well yeah Standard liters per minute or SLM, specifically refers to flow rates measured in the U.S.
So the “other” measurement would evidently be Europes “Normal liters per minute”.
What the difference is, I couldn’t tell you.
