Most economical Height/Diameter ratio - Field Fabbed Tanks
Most economical Height/Diameter ratio - Field Fabbed Tanks
(OP)
Are there any references available on the internet to determine the most economical H/D ratio for FF tanks ?
I was told that a tank with the shell height should be evenly divisble by 8 ( 24,32,40,48 etc) was most economical for CS. For SS tanks, the shell height should be evenly divisble by 4.
Aside from that, the diameter should be adjusted so that the H/D ratio is between 1.0 and 1.2.
Now I know that other factors can control this selection (i.e. soil loadings, need for agitation etc)
But what is the general rule of thumb and where can I find it......???
Thank You and Best of luck with the new forum..

Either way is acceptable.
Are you saying with the H/D ratio that a 40ft high tank should be between 40ft and 48ft diameter?

Larger diameter floating roof tanks optimum range e.g.55 meters upward for safe,stable and smooth operation and recommendable Height to Diameter ratios i.e 1:5 or 1:7 etc.
Any thoughts/Tips?

For larger capacity tanks, I also agree to max out the height based on the soil conditions as the roof cost becomes a major factor. My experience is in low seismic regions, this philosophy may differ for high seismic regions.
As for the plate widths, I would leave the fabricator some flexibility with the dimensions (if possible) based on the plate dimensions that are available to them.
Having said all of that, defining a general rule of thumb is very difficult due to the many variables in the design.
