An experiment was carried out in Al-Rifai District - Dhi Qar Governorate, to study the effect of the distance between drippers and their discharge on friction losses, coefficient of variation, and emission consistency of the drip irrigation system. Spiral drippers with a design discharge of 4 and 8 L.hr" 1 . While the emitters were installed at distances of 20, 40, 60 (cm). The actual discharge of the droplets was measured and the friction losses, emission consistency coefficient, and discharge variance ratio were calculated. The results showed that the distance between the emitters 60 cm gave the lowest percentage of friction losses, which amounted to 0.165, 0.204 (m) for drippers with design drainage of 4, 8 L.hr -1 . The best values of the emission consistency coefficient and the variance ratio in the emitters discharge were 95.44 and 28.41% when using the 8L.hr -1 and the distance between the emitters is 60 cm, respectively.
