Irrigation and Melioration

Abstract

When the fluid moves in pressure pipelines, the determination of the coefficient of hydraulic friction is very important. To determine the coefficient of hydraulic friction during the movement of a homogeneous fluid, there are formulas that have a theoretical basis and experimental confirmation. Determination of the coefficient of hydraulic friction is much more complicated when there is a turbid flow in the pipeline, in such cases laboratory experiments are necessary. The article deals with the issue of experimental determination of the coefficient of hydraulic friction during the movement of slurry in pressure systems. The experimental results are processed based on the laws of mathematical statistics. For the practical application of the data obtained, the theory of hydrodynamic similarity was used.
