Best way to tune cap tube??

[theclash]

I've been searching the forum looking for a decent explanation on how to fine tune cap tube length and have found nothing definitive. Would the best way be to start with a cap tube slightly longer than what I think I will need, shorten inch by inch as I load test, and braze new cap tube when my temps don't improve?

Unfortunately :( that is the best way I've found to do it.

Sorry to say, but I havent found anything definitive yet. The best thing I came across is a very practical guide by Gary Lloyd:

Also I included a few files you might find helpful.

I think that those who really know what they're doing in the whole thermodynamics field calculate the flow rate required for a given load at a given temp then can use a table like the one above to pick out a size and i.d

Nobody calculate the accurate length needed, even industry doesn't, the best way to know the captube size is to make experimentations on a system and you get a good information of the variation of flow rate involved by different captube length to set a good length on systems.
