the Cross-flow the resistance was pretty low, comparatively speaking.

question. I'll be happy to study these equations somewhat (I started out
in astrophysics but ultimately ended up in computer science... and that
was 30 years ago almost; so I'll get some of it at least). But sounds
like maybe the bigger condenser may not be necessary, so long as I
increase the flow...
That's helpful in itself. Thanks
