ON THE DEPENDENCE OF HYDRAULIC RESISTANCES OF MACHINE AND DERIVATION CHANNELS OF HYDROELECTRIC POWER PLANTS ON PRESSURE LOSSES OF HYDROPOWER FACILITIES

Abstract

The question of the study of hydraulic resistance to fluid movement in a turbulent regime has more than a century of history, but it continues to be relevant to this day. The extensive construction of numerous free-flow watercourses, as well as machine and diversion channels of hydropower facilities, requires scientifically based calculation methods. For the correct establishment of hydraulic calculation methods, a sufficiently deep study of the physical essence of the phenomena occurring in free-flow flows is necessary.
