Taking the sprinkler head of 30PSH as an example,the method of perpendicularity is used to analyze the influence of combination distance, work pressure and layout form on uniformity coefficient in irrigation.The effect sequence is that combination distance is stronger than work pressure, and then is layout form. When the isosceles triangle layout is applied, combination distance is 1.2 R and work pressure is 0.35 MPa, then the best uniformity coefficient will be got. These conclusions have very importan...
