You make a clear statement of what is obviously false, for any plain
meaning of "dissipate power".

The maximum attainable work from a compressed air source, being drawn
through a close restriction, is less than the maximum work attainable drawn
through a more open restriction. That difference is the loss of power
directly attributable to the difference in restriction. This is true
whether one presumes isothermal or adiabadic conditions, or for any ambient
pressure, etc.

It seems hopeless to correct your misunderstanding.

Nevertheless, I presume you try not to pinch your air hoses, even though
you believe restricting flow doesn't "dissipate power".
