| This Research aims to obtain appropriate management for Impact sprinklers to overcome the problem of soil damage due to droplets’ kinetic energy. Nozzle pressure and diameter had a major influence on droplet size which highly affects the droplet kinetic energy. Experiments were conducted at the National Irrigation Laboratory of Agricultural Engineering Research Institute (AEnRI), Dokki, Giza, Egypt was chosen to represent the engineering data of the selected impact sprinkler, riser and operating pressure. Two different nozzle diameters 3.2 mm and 3.9 mm were examined in this work at three different pressures range: 175 kPa, 200 k Pa and 225 kPa Then we found the results as follow: - Precipitation rates at pressure 225 kPa are the most regular rates, followed by pressure 200 kPa followed by pressure 175 kPa for the two tested nozzles. - Droplet Kinetic energy at the end of the wet diameter at nozzle diameter 3.2 mm is 26.83 J (10)-3, 23.9 J (10)-3 and 18.3 J (10)-3 at pressure 175 kPa, 200kPa, and 225kPa respectively, and at nozzle diameter 3.9 mm is 37.7 J 10-3, 35.78 J (10)-3 and 27.82 J (10)-3 at pressure 175 kPa, 200kPa, and 225kPa respectively. | ||||
