Determination of head loss in water pipes

This article is devoted to the problems of water supply to the population, which are associated with the current water management situation, such as the shortage of water resources, the decline in the quality of surface and groundwater, the technical condition of pipelines. In this situation, there is a need to eliminate or mitigate the current situation, so the study of hydraulic friction losses in water conduits is of national economic and scientific importance.The article deals with the issues of determining the pressure loss in water pipes under various modes, the causes of clogging of pipelines in water supply systems and the basic formulas of engineering hydraulics under conditions of insufficient water supply to the population. Solving the problem will increase the reliability of pipeline operation, meet the requirements of the population, and meet the minimum of the reduced costs for construction and operation.
