if there was a piston sitting in the tube , then
your calculations state that the piston would not move.

or would the piston move.

would the pressurized air present a force to the piston?

I already know it would , but for some reason it seems
that you think it would just sit there even though it
only has 14.7 psi on the other end.

Im about to throw my arms up in the air and mark you off as a candidate to use as a tool to deny funding that should apply to work with the idiots at the D.O.E.

3/4 inch of dust build up on the moon in 4.527 billion years,LOL and QM is fantasy science.
