📖 Hydraulic Performance of Drip Emitters under Field Condition. For Irrigation Engineers and Planner.

Irrigation performance assessment is of high priority in irrigation research priorities needed to solve the problem of irrigation development & management. Practically many irrigation systems are performing below their capacities. This may lead to non-uniform and unreliable water distribution. Therefore, a good starting point is to assess the performance of available irrigation systems in order to identify areas of lapses in the system design and make amends. A field study was undertaken to evaluate the performance of on-line non pressure compensating of 2, 4 and 8 lph discharge ratings. The system was tested for its uniformity coefficient, emission uniformity, manufacturing coefficient of variation and head-discharge relationship.
