Abstract
This study looked into how changing operating pressures affected the uniformity of water distribution under overhead floppy sprinklers. Coefficient of uniformity (CU%), distribution uniformity (DU%), and application efficiency of the low quarter (AELQ%) were calculated under five levels of operating pressure (1.0, 1.5, 2.0, 2.5, and 3.0 bar) under overhead height (3 m) for tow devices of floppy sprinkler, original type (FS1), and local type (FS2) at the experimental farm of ElSalhia, ElSharkia Governorate, Egypt during the 2023 season. The findings showed that the overhead floppy sprinkler with the highest CU, DU, and AELQ values (82.37%, 72.91%, and 65.81% for FS1) and 80.75%, 72.88%, and 65.59% for FS2), respectively, required an operating pressure of 2.0 bar and a height of 3 meters. Additionally, the results demonstrated that, under the identical operating pressure conditions, the FS1 sprinkler's CU, DU, and AELQ values are higher than those of the FS2.Finally, it is recommended to use the original floppy sprinkler.
