Hydraulic head losses on pressure pipelines of hydropower plants

This article discusses issues related to the study of hydraulic resistance on pressure pipelines hydropower plants pumping turbid water flow. Experimental studies, carried out in laboratory conditions a bench model, pursued main goal studying nature changes losses various characteristic sections for All experimental studies were with different local resistances and along length section.To clarify general picture change pipeline clean flow, six series experiments out. Each included at least 4 differing flow rate supplied model installation. The rates as follows: Q1 = Qmax; Q2 0.6Qmax; Q3 0.3Qmax; Q4 Qmin.Experimental have been has studied.
