The results of experimental study of swirling flow hydrodynamics in an open cylindrical channel are considered. The channel diameter is 20 mm, the length is 280 mm; it was supplied with tangential swirl generator at the inlet. The static and total pressure fields, surface swirl flow angle, hydraulic losses in the channel and tangential swirl generator are given
