IrrigationQuestion 13 of 100
Head-to-head spacing of spray heads means each head is spaced so its throw reaches what point?
a.Halfway to the next head
b.The base of the adjacent head
c.Twice the distance to the next head
d.Only the center of the zone
Explanation
Head-to-head coverage, also called 100 percent overlap, spaces heads so each one throws water all the way to the adjacent head. Because spray heads apply less water at the outer edge of their radius, this overlap is required for even coverage. Spacing heads farther apart creates dry rings and poor uniformity.
