Abstract
The article discusses issues related to the determination of hydraulic resistances and the coefficient of hydraulic friction based on scientific research conducted relatively recently. Formulas for determining the coefficient of hydraulic friction by various authors and studies on determining the value of hydraulic resistances are presented, which propose a non-traditional method for determining the average speed along the pipeline section. The works studying the influence of liquid temperature and the introduction of polymer additives on the amount of hydraulic losses are analyzed.
