Abstract
The uniformity of irrigation with wide-range sprinklers is largely determined by the sprinklers installed on them, their design features, the distance between them along the pipeline and the water pressure. The purpose of the study was to select a model of sprinklers that ensure uniform watering when operating at low pressure and determine the optimal distances between them. Based on theoretical assumptions, the popular PC-S3000 and PC-R3000 models were selected for experimental research. Five nozzles of different diameters were selected for each sprinkler. The operating pressure varied in the range of 0.06-0.14 MPa. The surfaces were built with a superimposed layer of precipitation. It was determined that the irrigation areas under sprinklers located at a distance of 1 and 5 meters from each other have significantly less uniformity than those located at a distance of 2-4 meters. The interval of installation of sprinklers 3 meters apart from each other of the PC-R3000 model gives a Christiansen coefficient of 86.8%.
