[TowerTalk] inductance of tubing vs bar or strip

[Pete Smith N4ZR]

Can anyone suggest where I can find a calculator for the inductance per 
foot of copper tubing compared to the same length of copper bar or 
strip?  I'm looking to understand the potential utility of using 
soldered copper tubing for a ground bus, as compared to copper strip/strap.
