I read through the BSHB "Keg Line length balancing" ( http://beersmith.com/blog/2011/07/14...of-draft-beer/ ) and decided to go get some tubing and get it done. I calculated that I needed 5 ft of 3/16 vinyl tubing. I got to the store, and picked it up only to find when i got home I accidentally got 3/8 tubing. Is there anywhere online I can find the resistance of 3/8 tubing? Or a table of different resistances of different tubing?
