Abstract

The purpose of the work is to determine the hydraulic resistance of pipes with local turbulators. To achieve this goal, an experimental study was carried out, results were obtained and generalizing empirical dependences on the hydraulic resistance of pipes with local turbulators were proposed. The results obtained differ from the known ones in that for the first time empirical dependences were proposed to determine the hydraulic resistance in pipes with local turbilators, which made it possible to significantly increase the reliability of the results obtained.
