Pro/Forums - View Single Post - performance related to down sizing tubing, and flow related to smallest ID in loop

i was having a bit of a heated debat with a guy in the chat... i would like to see other peoples input on these 2 topics.

1: This is the question i am mainly interested in... When using 1/2" barbs, their ID is ~3/8". Silicone tubing with a 3/8" ID stretches over these barbs nicely. It would be easier to manage smaller tubing, and I do not see much potential for 1/2" ID tubing because your barbs are limiting the flow. In the majority of systems running 1/2" barbs (with ~ 3/8" ID), wouldnt 3/8" ID tubing be more ideal? would 1/2" tubing make any real difference here?

2: (this is basically the same question.. just a slight difference) If you have all 5/8" barbs (~1/2" ID), EXCEPT your water block which has 1/2" barbs (~3/8" ID)... wouldn't it STILL make sense to just use 3/8" ID tubing because the block would be limiting the overall flow. would 1/2" tubing make any reasonable difference?

(of course gettin a different block would be ideal, but i am looking for an answer on the setup AS IS)

*note that all of the above are assuming that you compare the exact same system, but just different size tubing

please make sure we know if you are referring to question #1 or #2
