Abstract

Hydraulic properties of LOW PRESSURE drip irrigation systems were studied under laboratory conditions, with the use of pipes prevalent in Iran. The effects of various heads ranging from 0.45 to 1.8m were evaluated on lateral pipe of an outside diameter of 32mm and lengths of 16, 30, 60 m, and as well on a lateral pipe of a length of 16 m, and outside diameters of 16, 20, 25 and 32mm, on the hydraulic characteristics consisting of: average emitter discharge, variation coefficient, uniformity and loss. Emitters employed in the study were micro-tubes of lengths of 0.7m and outside diameter of 3mm inserted into the lateral at 1m intervals. Results revealed that the LOW PRESSURE TRICKLE IRRIGATION system supplied the necessary discharge along all the lateral lengths and diameters up to the end of the line. Moreover, a test of the effect of LATERAL LENGTH AND DIAMETER on emitter coefficient of uniformity indicated that a desirable uniformity is obtained in the lateral of the length of 89m, and 16 mm outside diameter accompanied by the least head.
