Evaluation of the common emitters recently used in Egypt

Abstract :

Emitter is the main device of a drip irrigation system. The study was conducted to assess the performance of emitters recently used in Egypt. Drip irrigation systems required adequate uniform distribution of emitters discharge over the irrigated area. The manufacturing variation in emission devices (C_V) is play a vital factor influencing the flow uniformity among emitters of a drip irrigation system. C_V is a dimensionless value calculated by dividing the standard deviation of the flow rates of a suitable sample of emitters by the mean flow rate of the sample tested. Emitter manufacturing uniformity must be measured when choosing an emitter for a system, and when designing the system to meet predetermined efficiency aims. The main purpose of this paper was to determine typical coefficient of manufacturing variation values for emitters commonly used in Egypt. Experiments were conducted to determine the emitter discharge–pressure relationship. These results will allow designers and operators of drip irrigation systems to be more aware of the capabilities and limitations in their systems. The pressure of 0. 5, 1.00, and 1.50 bar was set turn wise and the discharge rates were calculated separately for all set pressures. The C_V ranged from 0.031 to 0.045 with an average of 0.038 for the model tested. The discharge – pressure relationship, emitter discharge exponent, was tested. A correlation was evident between C_V and the operating pressure.
