DESIGNING TRICKLE IRRIGATION SYSTEM WITH PRESSURE COMPENSATING EMITTERS
The objective of this study was to design the trickle irrigation system by compensating emitters (Katif) and The experimental work was carried out in the experimental farm of faculty of Agriculture, Menufia university during 2018. A field experiment was conducted for 50 m and 75 m of lateral length with outer diameter 16mm and φ13.6mm inner diameter under discharges of (2,4and 8 L/h) and spacing between emitters 0 .5 m. Several points were taken 2 m apart into considerations, such as emitter characteristic friction losses, manufacturing variation, discharge and hydraulic variation. Emitters were tested at 50 ,100 ,150and 200 kpa to determine the pressure –discharge relationship and the uniformity parameters. The found results showed that the exponent values for the compensating emitters under study ranged from 0.06 to 0.2. The measured coefficients of manufacturing variation values for compensating emitters were in the excellent class. As such the variation of discharge through these laterals is restricted by limiting their number to have emission uniformity, EU, greater than 90%.
