Irrigation and Melioration

Abstract

In many sectors of the water economy, one can observe the movement of a sediment stream in pressured systems. The pressure losses in the liquid and sediment joint stream are different than the movement of a single-phase flow according to their pressure loss. In this case, some difficulties arise in determining the coefficients that affect the flow rate and the average flow rate. In the article given theoretical and experimental foundations for determining the hydraulic flow parameters in during the movement of a sediment and liquid flow. Theoretical studies are based on the laws of energy conservation, and laboratory studies are aimed at determining the sediment flow rate. As a result of theoretical and experimental studies, a new dependence of the flow coefficient on the mode of movement was established and it is recommended to place it in the turbid flow rate formula.
