Abstract

 

The use of rectangular spraying can reduce the water and energy requirements in variable pressurized irrigation system. The water application cost can be minimized in rectangular spraying after theoretical analysis. The aim of this study was to achieve rectangular spraying by variable pressures of the pump. Experiments were carried out on a turbo-type whirling sprinkler to determine the spraying effect. Water distribution by the sprinkler was evaluated in an indoor facility. The three-dimensional water distribution figure was drawn using Matrix Laboratory (MATLAB). The result demonstrated that rectangular spraying can be achieved.

 

Key words: Rectangular spraying, sprinkler, wetted radius.
