A critical analysis of these methods was carried out. The methods of hydraulic calculation of pressure distribution pipelines proposed experimentally in Ukraine have been verified. An experimental stand was designed and manufactured for experimental determination of the values of the flow coefficient of the output cylindrical nozzles with a lateral, orthogonal to the longitudinal axis of the nozzle, jet entry into the nozzle, at different values: the angle of the jet diversion from the main flow in the distribution pipeline; ratios of the cross-sectional area of the outlet nozzles and the distribution pipeline. An experimental stand was also designed and assembled for the experimental study of uneven operation of pressure distribution pipelines depending on different angle values and area ratios. Graphical dependences of the value of the flow coefficient for cylindrical outlet nozzles with lateral, orthogonal to their longitudinal axes, jet inlet for five values of the angle and five values of area ratios were obtained experimentally. The scientific and practical results of the NDR were used in the educational process of the Lviv Polytechnic National University when teaching the subject "Hydraulics and fire-fighting water supply".
