Abstract
The study presents the manners of determination of the Darcy friction
factor λ for a homogenous hydromixture of alum sludge of varied hydration
and temperature for the laminar flow zone. 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).
