تحديد ضغط التشغيل للمرشات و تقييم ادائها

The agriculture sprinklers are considered an important component of any sprinkler irrigation systems. The efficiency of sprinkler irrigation depends on the quality of used sprinklers. In this research, the evaluation of some available local sprinklers has been done in order to determine their technical specifications. The appropriate operating pressure of the studied sprinklers has been determined. Five types of small rotary widely used sprinklers have been chosen, three of which have two nozzles and the others have one nozzle. Discharge from each nozzle and the radius of the sprinkling in case of closed hall without rotation have been also determined. It was found that using appropriate operating pressure of sprinkler decreases the power of pump for about 55%.
