Description	A number of papers has aimed at an analytical solution of the axial annular flow of power-law fluids, especially the relation: volumetric flow rate vs. pressure gradient. No complete analytical solution has been yet achieved. The only analytical solutions - that have been hitherto derived - concern the limiting cases of a geometrical parameter κ (inner-to-outer diameters ratio) or a flow behaviour index n. The present contribution discusses an applicability of these limiting solutions for a broader region of entry parameters and proves that in many cases usage of these relations is fully acceptable (and comparable with an inaccuracy in experimental determination of flow behaviour index n and consistency parameter k of the power-law model).
