| Abstract | ||||
| The influence of dripper geometric map on hydraulic properties of the dripper gets wide application in drippers performance. Three types of drip geometric map (verticalhorizontal, and in-out), and three angles of water entrance to the drip base (45°.,90° and 180°) two drip water path length, use 20 to 25 mm and 25 to 30 mm were used. The following results are obtained:- 1- For the effect of dripper geometric map shape on drip hydraulic properties the vertical and horizontal ones were more efficient than the in-out one. 2-The water angle 180° was more efficient than others in dripper's performance compared with the other degrees (45° and 90°). 3- The effect of path length on dripper performance. As the path length decreased to 20 mm the dripper performance increased (EU %) also CV achieved the highest degree in CV classification (Excellent) according to ASAE. Also, path length between 25 to 30 mm recorded the lower hydraulic performance of drippers. The recommendations of this research are: use a geometric map of drippers, either vertical or horizontal, with the angle of water entrance through the base of drippers (180 °) with the length of the path of drippers not exceeding 25 mm. | ||||
