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

Boy, I wish I had 2 flowmeters.
You don't need them! You understand
the physics behind it instead, which
is better.

You two may understand the mass flow, but if you think it about it a little
more, you will see that Richard Kinch is correct, the transformer analogy is
not applicable. This is a thermodynamic problem, and an interesting
illustration of how inefficient it is to compress air to a high pressure if
it is only going to be used at a much lower pressure.
