Default SCFM vs. CFM, also air flow/pressure across a regulator

You make a contemptibly false statement, ignorant of even high school
physics.


Perhaps some high school physics classes leave their students ignorant
enough to believe your claim. But my university degree in physics says
you're wrong. A *rate* is a measure of how quickly *something* else is
converted, moved, or otherwise transferred past an observation point.
It is that *something else*, in this case energy, which does the moving.
Power is merely an observation of that energy flow past a fixed point.

Consider this, if power can flow, what are the units of that flow?
It would have to be a rate of a rate, ie kg-m/sec/sec, and that
isn't the units of a watt. What sort of meter would you need to
measure it?
