Annular pumping is based on plunging of a circular rod into an axisymmetrically located circular cup containing the experimental sample. Formerly this method was successfully applied to power-law, Bingham and Herschel-Bulkley fluids. The aim of this contribution is to present a sufficiently simple userfriendly procedure how to determine the individual rheological parameters appearing in the Vocadlo model (sometimes called Robertson-Stiff one) - yield stress, consistency parameter and flow behaviour index.
