Calculating Column Height

Post by Copperjohn »

How does one determine proper column height for a particular diameter pipe? I've searched the forum and I came up with what was suggested as a rule of thumb. The rule of thumb was that height should be 12-20 times the diameter of the pipe. So for instance a 6 inch column should be 6-10 ft tall.

Couple of questions...
* What occurs if the column is shorter than suggested by rule?
* Why would one choose the lower end of the range. Why choose the upper end?
* Lastly if this rule of thumb is a good rule of thumb then why are most of the 4 inch builds on this site (including mine) well short of what is suggested by the rule?
