The work is devoted to development of methods of determination of the hydraulic resistance in smooth tubes by generalization of the available experimental data. The analysis of the data on the measurement of hydraulic resistance, it was noted that regardless of the path circulation, coolant and other factors, the change in hydraulic resistance has the same nature. This phenomenon gave rise to the idea to summarize the available experimental data and to create a generalized dependence of hydraulic resistance, which will facilitate the work of designers in the development of equipments with circulation paths. In addition to the existing experimental data, it is a test. For these purposes was designed and created installation, includes pipes and several kinds of local resistance: the diffuser, the sudden expansion, turns. Cranes allow you to change the route of coolant circulation and, consequently, the set of passable local resistance
