| Abstract | ||||
| A selected rotating sprinkler was tested in radial test within 100 to 300 kPa under nozzle #8 with 25º trajectory angle and #3 with 11º and 25º trajectory angles. K— Rain 75 pop-up sprinklers were selected due to having 12 different nozzle trajectory angles. Sprinkler discharge application rate, and pattern radius were measured at different operating pressures in individual test. For 300kPa high distribution uniformity was obtained for nozzle #8 with 25º trajectory angle in square and rectangular layouts. Square layout achieved distribution uniformity higher than rectangular layout for overlapping 100and 80%. Friction loss for a given pipe length was found in designing optimal main ,sub-main and lateral diameters under optimal nozzle angle, pressure, layout and overlapping. | ||||
