this is not yet defined unambiguously. I guess it is about the inner
diameter of something? Or sometimes it is about the inner diameter (e.g.
tubes, pipelines, pipes, etc.), while in other cases it is the outer
diameter (e.g. tree trunk, pole, tower, ...)? Maybe we should
distinguish these, at least for hollow things?</div></div></blockquote><div><br></div><div>Diameter is indirectly linked to fluids ability to flow inside the pipe.
