It is necessary to test the micro-sprinkler so that the designer can select the micro sprinkler best suitable for a specific requirement and a system can be designed accordingly. Two different types of micro-sprinkler viz. type A (26 lph), type B (50 lph) were selected for the performance test. The performance evaluation for micro-sprinklers was carried out for different operating pressure i.e. 1, 1.5, 2kg/cm2. The estimated value of uniformity coefficient was found to be in the range of 88 to 92% for type A and 82 to 91% for type B micro-sprinkler. The estimated value of nozzle exponent was f...

The estimated value of uniformity coefficient was found to be in the range of 88 to 92% for type A and 82 to 91% for type B micro-sprinkler. The estimated value of nozzle exponent was found in recommended range. The type A micro- sprinklers were classified as average and the type B micro-sprinklers were also classified as average on the basis of coefficient of manufacturing variation. The uniformity coefficient, distribution uniformity, and distribution characteristics increases with increase in operating pressure for both the micro-sprinklers.
