The rheological evaluation of the hydromixture as a viscoplastic body has been conducted with use of measurements of viscosity. The curves of flow were approximated with use of the generalized Vočadlo model. The Darcy friction factor λ of the pipeline was determined with use of the non-dimensional criterion λ(Regen) and λ(Re, He).}, type={Artykuły / Articles}, title={Characteristics of Laminar Flow in Pipelines of Homogenous Alum Sludge Approximated with use of the Vočadlo Model for Viscoplastic Liquids}, URL={http://www.czasopisma.pan.pl/Content/85982/PDF/aep-2014-0037.pdf}, doi={10.2478/aep-2014-0037}, keywords={Alum sludge, rheology, hydrotransport, Reynolds number}, }
