“…The optimization of irrigation water requires both the correct design of the water distribution system and the choice of management options that limit crop water requirements, without affecting crop yields and quality (Autovino et al 2016). Fundamentally, the success of a drip irrigation system is affected by imprecise design or inaccurate management.…”

Objective: The objective of this study was to investigate the effect of different pipe wall thickness on the flow rate of cylindrical type integrated emitters used in drip irrigation pipes.Material and Methods: Cylindrical in-line integrated type, non-pressure compensated two drip emitters were considered within the scope of this work. The drip emitters (E1 and E2) manufactured by two different companies were integrated in 1.1, 0.9 and 0.6 mm wall thickness pipes. The emitter flow rate measurements were carried out at five different pressure levels for all drip irrigation pipes. Results:The operating pressure and flow rate relationships for the emitters and drip irrigation pipes at each pipe wall thickness were also determined. In general, it was also observed that when the wall thickness decreased sequentially from 1.1 mm and 0.9 to 0.6 mm, average emitter flow rate increased about 30% based on the brand of the emitter as well as on pressure. The variation of emitters flow rate based on the wall thickness at the nominal pressure of 100 kPa was analyzed statistically. Based on the results, these variations were found statistically significant (P<0.05) for all drip irrigation pipes equipped with E1 and E2 type emitters. Conclusion:The results of the study clearly showed that these wall thickness changes caused significant changes in emitter flow rates. ÖZAmaç: Bu çalışma, aynı tip damlatıcının farklı et kalınlığına sahip damla sulama borularına entegre edilmesi durumunda, damlatıcı debisi üzerine etkilerini ortaya koymak amacıyla yapılmıştır. Materyal ve Metot:Çalışmada iki farklı firma tarafından imal edilen türbülanslı akış rejimine sahip, boru içine entegre, silindirik tip, basınç dengeleyici özelliği olmayan damlatıcılar ele alınmıştır. İki farklı firma tarafından imal edilen damlatıcılar (E1 ve E2) 1.1, 0.9 ve 0.6 mm et kalınlığına sahip borulara yerleştirilmiştir. Damlatıcı debi ölçümleri beş farklı basınçta gerçekleştirilmiştir. Denemeler sonucunda, her bir boru et kalınlığındaki damlatıcı ve damla sulama borusu için basınç-debi ilişkileri ortaya konulmuştur.Bulgular: Genel olarak boru et kalınlığının 1.1 mm'den, 0.9 mm'ye ve en düşük değer olan 0.6 mm'ye düşmesi durumunda, üretim yapan firmanın damlatıcısına ve deneme basıncına göre %30'lara varan oranlarda artış meydana geldiği gözlenmiştir. Çalışma kapsamında, 100 kPa nominal çalışma basıncında damlatıcı debilerinde, et kalınlığına bağlı olarak meydana gelen bu değişim değerleri istatiksel yönden araştırılmış ve Duncan istatistik analiz sonuçlarına göre damlatıcı debilerinde meydana gelen değişimin E1 ve E2 marka damlatıcılı damla sulama borularının tümünde istatistiksel olarak önemli (P<0.05) olduğu bulunmuştur.Sonuç: Çalışma sonuçları açıklıkla göstermiştir ki boru et kalınlığındaki değişimler, damlatıcı debileri üzerinde önemli değişikliklere neden olmaktadır.
