Does anyone have such a beastie? I can't seem to find anything on the tinterweb

Hi Mike
Is this for distributor lead sizing ?

I have to make a 1 ton liquid condenser and I have the tube runs and diameter for a air cooled one. I'm trying to match, as closely as possible, the volume, and pressure drop of the current air one. I will be up sizing the tubing from 4 parallel runs of ~5mm or 3/16 tube to 5/16 tube with perhaps 2 parallel runs. Sound simple enough, haha.

Engineering toolbox seems to stop at 1/2" tube and the tables I have from Copper institute (not institute of UK policemen), seems to stop there as well.
