Abstract
To assess the effectiveness of a full-size mobile universal fire extinguishing system, fire tests of the developed layout of an experimental mobile universal fire extinguishing system were carried out, taking into account the requirements of national standards, which determined the choice of the operating pressure range and nozzle diameters. Numerical values of the duration of the supply, the length of the jet and the rate of discharge of fire extinguishing agent from the vessel of the layout of a mobile universal fire extinguishing system from the diameters of the nozzles with a change in pressure are obtained. The results showed that
 the duration of the supply and the length of the jet of fire extinguishing agent, regardless of the diameters of the nozzles, depend on the pressure, the flow rate and outflow rate of fire extinguishing agent depend on both the diameters of the nozzles and the pressure. The relationship between the parameters of the layout and its extinguishing capacity has been determined, which confirms the declared capabilities of its working cycle.
