Summary:

I have come across this equation on a research paper to get the diameter of a dryer using its volume and Length/diameter ratio. I was wondering if anyone had seen it before/ knows how it is derived as I have not seen it in any books. Thanks

Looks like it is just the volume of a cylinder, re-arranged, and maybe scaled so it isn't full.

The equation is dimensionally incorrect and makes no sense to me.

The equation is dimensionally incorrect...
That's common in "rule of thumb" or "rolled up constants" equations.
