NOTE
The area-coverage and dispersion-uniformity of a layout of sprinklers is influenced by the alignment
of the sprinklers.
The common types of sprinkler alignment are:
Rectangular alignment
Triangular alignment
Isosceles
Equilateral
Do not confound isosceles with equilateral:
•
An isosceles triangle is a triangle in which two sides are of equal length. The distance between 2
adjacent sprinklers on the same lateral (a) is not equal to the distance between 2 sprinklers on
adjacent laterals. The height of the triangle represents the distance between adjacent laterals (b).
Isosceles is usually referred to In open-field applications.
•
An equilateral triangle is a triangle in which all three sides are equal. The distance between 2
adjacent sprinklers on the same lateral is equal to the distance between 2 sprinklers on adjacent
laterals. Equilateral is occasionally referred to in orchards due to the tree planting pattern.
