Analysis Of Center Pivot Irrigation System By Experimental Method

摘要

The objective of this project is to design a center pivot irrigation system and determine the efficiency of the system by using experimental method by build a model of the system. For that, a literature study is carried out to understand the theories of center pivot irrigation system. Center pivot irrigation system is the system that can rotate 360 degree around the center pivot. Before model build, the theoretical calculation need to be done to calculate the specification of the model. The model of the experiment purpose build not included the rotation part because the rotation part not gives an effect to the water flow. The experiment procedure follows the standard of North Carolina State University that conducts this type of experiment. From the experiment, the uniformly efficiency of the irrigation system can be defined. Scaled model use in this experiment to determine the uniformly efficiency by using specification from the theoretical calculation. From the previous experiment the uniformly efficiency of the irrigation system is 50%-60% and the uniformly efficiency of center pivot irrigation system is about 75%-90%.
