From a practical engineering point of view, the size of a ,pipe, is specified by its ,diameter, since that is what is easy to measure, so you might as well use the ,diameter, for Re also. For a ,pipe, that is approximately ,circular,, you might decide (by a similar sort of physical argument) that the circumference of the ,pipe, is really the most important ,length,, and therefore compare the results with ,circular, pipes by using an "equivalent ,diameter,…
