The article describes the influence of the spraying angle on the distribution of the sprinkling intensity in the spray generated by the water nozzle Rosenbauer SELECT FLOW RB 101 EN. A partially modified laboratory stand normally used for testing of water nozzles was applied to carry out the experiments. Measurements of sprinkling intensity were made using the refined test method derived from the old Polish standard PN-89/M-51028. This parameter was determined in a weight-volume manner using measuring containers. The paper presents only the results of tests carried out for a flow rate of 400 dm3/min and three spraying angles: 30°, 60° and 90°. The obtained results clearly indicate that the spraying angle is a very important parameter affecting the distribution of sprinkling intensity in spray jets generated by Turbo water nozzles. It has been observed that along with the change of the spraying angle, the values of many parameters adopted for analysis describing the distribution of the sprinkling intensity, such as the spraying surface and its dimensions (shape), the maximum length of the spray jet and the maximum sprinkling intensity, are changed. Finally, important conclusions were formulated both in the theoretical and practical aspects.
