Summary
<p>on the flow rate of cylindrical type integrated emitters used in drip irrigation pipes.</p><p>Material and Methods: Cylindrical in-line integrated type, non-pressure compensated two drip</p><p>emitters were considered within the scope of this work. The drip emitters (E1 and E2) manufactured</p><p>by two different companies were integrated in 1.1, 0.9 and 0.6 mm wall thickness pipes. The emitter</p><p>flow rate measurements were carried out at five different pressure levels for all drip irrigation pipes.</p><p>Results: The operating pressure and flow rate relationships for the emitters and drip irrigation</p><p>pipes at each pipe wall thickness were also determined. In general, it was also observed that when</p><p>the wall thickness decreased sequentially from 1.1 mm and 0.9 to 0.6 mm, average emitter flow</p><p>rate increased about 30% based on the brand of the emitter as well as on pressure. The variation</p><p>of emitters flow rate based on the wall thickness at the nominal pressure of 100 kPa was analyzed</p><p>statistically. Based on the results, these variations were found statistically significant (P<0.05) for all</p><p>drip irrigation pipes equipped with E1 and E2 type emitters.</p><p>Conclusion: The results of the study clearly showed that these wall thickness changes caused</p><p>significant changes in emitter flow rates.</p>
