At least 0.5 mm/h.
**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.
