SMART SPRINKLER: VARIABLE WATER FLOW USING NOZZLE SIZE CONTROL TO IMPROVE UNIFORMITY

Irrigation is essential in some places to perform uniform distribution of irrigation. As observed from previous literature and personal observation, some rotating head sprinklers cannot perform uniform water distribution. The target area of irrigation will not be able to achieve optimum water distribution. This project attempts to improve water distribution per unit area of rotating sprinkler, save water and it will improve irrigation of water to be more efficient. In order to achieve these, the author has taken initiative to design a smart sprinkler by introducing a combination of sprinkler turbine with nozzle flow control. Fabrication and testing is done to measure the water distribution to be compared with the original one. From the test result, the water distribution per unit area of Smart Sprinkler is found to be 13.419 ml/m2 while 12.191 ml/m2 for original model. As a conclusion, Smart Sprinkler has been able to increase the volume of water per unit area by 1.228 ml/m2 (10%
