The term in question is a RATE, neither a volume nor a pressure.
So.. you must specify the units when discussing the term - similar to when we are talking about the speed of an object; you have to state the units, if you want to ensure clarity.

volume/time or pressure/time
Everyone agrees it is a rate, the debate is whether it is a pressure rate or a volume rate

In a recent poll, 65% of respondents used SAC as volume/time and the other 35% used it as pressure/time. Less respondents used the term RMV, however, 97% used it as volume/time.
Question - Definitions for SAC and RMV?
This topic comes up over and over. Let's see what you think. Please vote once for SAC and once for RMV or vote for #5 and elaborate in your post or #6 if you don't know what this is all about.

This is off topic, but responding to

Well Galileo was condemned for his theory that the sun revolved around the earth, so.....
Galileo was not condemned for his promotion of the heliocentric theory of the solar system. Actually, the church liked the results of this theory since it more accurately predicted major Religious holidays. (At the time, Easter was moving more and more towards winter and its tough to celebrate new life when buried in snow).
Galileo was condemned because he falsely claimed that science was "Absolutely True" (Philosophical construct for that which never changes and can never be wrong ... but science is fallible (can be wrong) and changes (evolves with new data and understanding). It is useful only as long as its theories and laws provide useful applications for understanding the world around us).
He also wrote some extremely damning personal attacks on church clergy, especially the Pope.
So, had he just used his theory to predict holidays he would have been left alone (and he was told so by the church) ... it was insistence that he could never be wrong , as well as his extremely hostile views of clergy, that got him into trouble with the then all-powerful church.
Galileo was given house arrest; many others expressing belief in the heliocentric theory were burned at the stake. (At the time, anything contrary to Aristotle or Ptolemy was considered heresy).
So, while professing belief in the heliocentric theory was certainly a component, it was his arrogance, not natural philosophy (what later became science) that was a major component in his troubles. (not wise to bitterly satire an all powerful pope.)
Many moons ago I did a simplistic view of estimating breathing gas consumption at

Regardless of acronym volume/time is tank size agnostic. A cubic foot/liter is the same in any cylinder. I don't know why anyone would use pressure/time as an end point metric.
