This paper presents the results of experimental research aimed at determining the values of hydraulic resistance of fire three-way branching branches, which are used in fire conditions for simultaneous supply of extinguishing agents from several extinguishing devices. To conduct full-scale experiments was developed and mounted experimental and research installation, as well as diagnostic technique, which allows to obtain the actual values of hydraulic resistance of each branch of the fire three-way branching. The obtained experimental values of hydraulic resistance of fire branching branches are of great importance for the design of pumping and hose systems. They will allow to create more reasonable and effective schemes of organization of combat operations at the place of fire extinguishing, which, in turn, will increase the efficiency and effectiveness of fire units. Integration of these data into practical activities of fire departments will provide more accurate calculations in planning and organization of water supply, which is critical for successful performance of tasks on fire suppression and protection of population.
