The article is devoted to solving the urgent problem of increasing the efficiency of linking sections in the hydraulic calculation of pipeline systems to reduce the material and energy consumption of the system as a whole. The aim of the work is to create an effective method of hydraulic linking of sections of pipelines of microclimate support systems, namely the "two-diameter method" and the establishment of analytical calculations, provided that a meager percentage of the inconsistency of parallel sections.
Graphical and analytical dependences on basis of conducted theoretical calculations are presented. Analytical calculation dependences have been established under the condition of achieving a negligible percentage of in consistency of parallel sections. An effective method of hydraulic and aerodynamic linking of parallel sections of pipeline systems has been developed, namely the "two-diameter method".
