conversion factor such that cfm X psi X constant = watts.
What would that factor be?

Hmm. This might actually work out, the energy
stored in a pressure vessel is (IIRC) 1/2 P(sq) x V
so if you imagine an amount of air at a given
pressure passing a point in a pipe, then
that would be a time rate change of energy.

I think I would have to get ahold of my copy
of Haliday and Resnick at work, with the units
conversion tables at the back, to give the
constant though.
