Supplementary Comments about Dimensional Analysis

This result indicates that this problem can generally be studied in terms of eight pi terms, or - for a fixed geometry - in terms of four pi terms, instead of the original eleven variables we started with. It also shows the complexity of this currently used chemical engineering operation.

In addition to these supplementary comments about dimensional analysis, we can also discuss the following points, which are necessary to establish the list of variables. To do so, indeed, we have to ...
