abstract
A mini sprinkler system's hydraulic performance was assessed. Using a tiny sprinkler system with a "double nozzle - full circle" sprinkler at different sprinkler spacings (12 m × 12 m, 14 m x 14 m, and 16 m x 16 m) at three operating pressures (1.5, 2.0, and 2.5 kg/cm²), an experiment was carried out to assess the hydraulic performance. The optimal value of the jet break up index was found to be close to 4.0 at 1.5 kg/cm². The jet break up index was found to be in the range of 3.48 to 5.37 in all three operating pressures. Operating pressures of 1.5 kg/cm², 2.0 kg/cm², and 2.5 kg/cm²were used to generate the discharge rates of 440, 480, and 535 lph, respectively. The range of the uniformity coefficient for all system configurations was 81.28% to 92.23%. For 12 m × 12 m spacing at 1.5 kg/cm² and 14 m x 14 m spacing at 1.5 kg/cm², the uniformity coefficients were at par. The mini sprinklers' effective radius of discharge was measured at 6.35 m, 7.22 m, and 8.49 m, respectively, with operating pressures of 1.5 kg/cm², 2.0 kg/cm², and 2.5 kg/cm². Based on their performance, the 12 m x 12 m systems are operating at 2.0 kg/cm² and 2.5 kg/cm² of pressure.
