Annotation Experimental studies of the dependence of the coefficient of hydraulic friction λ on the Reynolds number Re at the stand “Hydraulics” in relation to the hydraulic drive. The formula for determining the coefficient of hydraulic friction for a turbulent regime of fluid motion is refined. Based on the results of studies, a graph of the dependence of the coefficient of hydraulic friction λ on the Reynolds number Re with an analysis of the four zones of this dependence is constructed.
