Abstract. Annotation. The article analyzes findings of domestic and foreign experts who investigated viscosity of the structured suspensions depending on the concentration of the solid phase. Results of experimental data analysis allowed validating of a universal function for approximating dependence between effective viscosity of the structured suspensions and their concentration. In the proposed functional dependence between the properties of the solid phase and chemical reagents, values of the proportionality factor and exponent are taken into account, which for water-coal suspensions depend on the diameter of the particles. The obtained results make it possible to determine and scientifically validate rate of hydraulic slope and diameter of the pipeline depending on the flow rate of the slurry, hence ensuring adequacy of the design and verification calculations of the hydrotransporting complexes, which pump structured suspensions, by granulometric composition of the transported particles.
Keywords: Keywords: structured suspension, effective viscosity, Bingham-Shvedov law, concentration, diameter of solid particles
