Coefficient of hydraulic friction of plastic pipes

Abstract

Pressure systems are widely used in almost all areas of the public economy related to liquids. For example, at present, in the supply of drinking water to populated areas in the world, in heating systems, in agriculture, in cleaning water basins from muddy flows, in the mining industry, in construction, in the raising of muddy flows, in the chemical industry, in the process of moving muddy flows at the same speed, in pipeline systems of viscous muddy flows efficient systems are being used for transportation and many other purposes. Recently, plastic pipes have been widely used in production. Such pipes are cheap, light, and resistant to various decays, and their installation is relatively easy. One of the main problems in the hydraulic calculation of pressure systems is the determination of the coefficient of hydraulic friction. Recently, many scientists working in the field have been improving the hydraulic calculations of such pipelines. Yet, there is still a lot of theoretical and experimental research to be done. The article presents a method for determining the coefficient of hydraulic friction in plastic pipes in laboratory conditions.
