I have a Kolsch in a 5 gallon corny keg in a refrigerator sitting at 38-40F. I was using the 4' line that came with my keg (3/16" ID PVC). Based on the traditional balancing calculations (L=(Pressure-1)/Resistance (3 for PVC)), I should be rock solid at this length when the keg is pressurized to 12 PSI. However, when pouring from the keg via picnic tap, I got a mammoth amount of foam and very little beer. I made a run to my LBHS and got a 10' line (picnic tap, 3/16" ID) and got a better pour, but still a little more foam that I'd expect. I already disassembled my dip tube and verified that it is clear. The line is all brand new including disconnect.
I'm fine with the fact that the 10' works better, but based on the calculations, this should provide too much resistance and not even put out liquid.
What am I missing?
