Emphasis is paid to the relation axial volumetric flow rate vs. axial pressure gradient. It is shown that for sufficiently broad region of entry parameters (rheological, geometrical, and kinematical) there is a possibility to derive quasisimilarity transformations enabling relatively easy determination of the above relation.
