Performance Evaluation of Mini-sprinklers

Mini-sprinklers of Rain port were selected for the performance test. The performance evaluation for mini-sprinklers was carried out for height of 1m. The estimated value of uniformity coefficient was found to be in the good range of 76 to 91percent for mini-sprinkler. The uniformity coefficient decreases with increase in mini-sprinkler spacing and increases with increases in mini-sprinkler pressure. As spacing increases from 3m x 3 m to 7m x 7 m the distribution uniformity decreases from 89 to 81% for mini-sprinklers, respectively. As pressure increases from 1.5kg/cm2 to 2.0kg/cm2 distribution uniformity increases for mini-sprinklers. Similarly, distribution characteristics increase with decrease in spacing and increases with increase in pressure of the mini-sprinklers. The distribution characteristic was found to be in the good range 43.61 to 55 percent for mini-sprinkler.
