it's easy to rationalize that overall airspeed would increase if and only if impacting molecules only came one way.
molecular motion vectors would be randomly distributed, 'windspeed' , being extremely slow compared to individual molceluar motion, plays in a
different league altogether.
i'm not saying that it can't have an effect, but to have one, you'd have to de-randomize molecular velocity vectors, by reflecting in a preferred
direction. even then, how far do you think does a gas molecule tavel before it hits another? i surface area comes into play, the pipes would have to
be extremely thin to get decent results, if i'm not mistaken. if you were able to affect volume, however... i don't know, though, from what you've
said, only the surfaces are important, right?
