Abstract Purpose. Study of the hydrodynamic parameters of the SPRUK 50/0,7 «Viking» fire barrel: the extinguishing agent consumption, the fire extinguishing agent delivery distance, the effective range of the sprayed spray of the extinguishing agent and the average irrigation intensity.
Methods. Experimental studies were carried out on the basis of the University of civil protection of the Ministry of Emergency Situations of Belarus in accordance with the requirements of STB 11.13.14-2009 Manual fire trunks. General specifications.
Findings. It has been established that the average fire intensity in the SPRUK 50/0.7 «Viking» fire barrel increases by 16% in comparison with the RSK-50 trunk, while the water consumption decreases by 14%. It should be noted that the range of the compact and sprayed jet is increased by 10 and 22 % in comparison with the Protek 360 and RSK-50 barrels, respectively, and the effective range of the jet by 14 %.
Application field of research. Extinguishing fires in a residential building using fire barrels with low consumption (up to 5 l/s).
Conclusions. As a result of the experiments, the effective range of the sprayed jet of the extinguishing agent and the average irrigation intensity were studied. As a result of the tests, an irrigation map was compiled for different positions of the flow controller, and it was also found that the actual values exceed the required values.
