The comparison of water distribution patterns of pop-up style sprinklers used in landscape irrigation

Abstract

In this study, water distribution of 4 different sprinkler heads (impact, gear drive, mp rotator, spray), used in landscape areas were determined for three different nozzles (small, medium, large) and for three different pressures (minimum, optimum, maximum). All measurements were performed with according to single head test method with three replicates in open field conditions. The Christiansen’s uniformity coefficient (CU) and distribution uniformity coefficient (DU) values are calculated for different sprinkler designs in the windless conditions. As a result, the CU values were found as 65,1-91,7% for impact, 63,2-91,3% for gear drive, 66,3-86,5% for mp rotator and 33,3-98,6% for spray; DU values were found as 42,0-82,8%, 47,1-86,7%, 45,1-81,6% and 0-97,3% for the above mentioned heads, respectively. © 2017 Namik Kemal University - Agricultural Faculty.
