Abstract

This investigation was carried out at Faculty of Agriculture  , Menoufia University, Egypt, on the Pop-Up  sprinkler at operating pressures   of 1.5 , 2 and 3bar, sprinkler emission angles of 45o , 90 o ,135 o, 180 o ,225 o, 270 o , 315 o and 360o  and riser heights   of 0.15 ,0.75 and 1.25  m . Discharge, uniformity distribution, coefficient of variation and  water losses percent of the sprinkler due to evaporation and water drift were determined . Results indicated that, when pressure decreases, discharge and coefficient of uniformity decrease . The percentage of the average decreasing for discharge were  28 and 42% and decreasing of coefficient of uniformity were  12.05 and 23.77% when using the operating pressures of  2  and 1.5  bar  compering with 3 bar resp. But increase coefficient of variation and water loss percent due to evaporation and water drift .Moreover, increasing the riser height at the sprinkler emission angles the discharge and the coefficient of uniformity  decrease . When angle increase from  45o to 360o the discharge and coefficient of variation increase from  o.115  to 0.362  m3 /h   and from   14.54 to 30.98 %  resp. ,while  coefficient of uniformity and  water loss percent  .decrease from  80.46 to 74.38 % and  from 17.85to 11.21 % resp. Due to interaction between the operating  pressure 3 bar and  height riser  of 0.15 m at emission  angle of  360o gave the highest value of the discharge , while at the  angle of  45 o gave the highest value of coefficient of uniformity.
