Spray Coverage Information
The theoretical coverage of spray patterns is calculated based on the included spray angle and the distance from the nozzle orifice. These values assume the spray angle remains constant, though in practice, it may vary at longer distances.
| Included Spray Angle | Theoretical Coverage at Various Spray Heights (in Inches) | |||||||
|---|---|---|---|---|---|---|---|---|
| 8" | 10" | 12" | 15" | 18" | 24" | 30" | 36" | |

How to Determine the Right Spray Tip Capacity
To select the correct nozzle capacity, consider the work speed, desired spray tip, and banding width.
| GPA Conversion Factors* | |||||||
|---|---|---|---|---|---|---|---|
| Width | 40° | 65° | 80° | 95° | 110° | 20" Spacing | 30" Spacing |
| 8" | 11' 6" | 5" | 4" | 3" | 2.50 | 3.75 | |
| 10" | 14" 8" | 6" | 5" | 4" | 2.00 | 3.00 | |
| 12" | 16" 9" | 7" | 5" | 4" | 1.67 | 2.5 | |
| 15" | 21" 12" | 9" | 7" | 5" | 1.33 | 2.00 | |
*To find GPA rate on band widths, multiply the tabulated GPA for ROW SPACING by conversion factors.
Calculation Formula
GPM (Per Nozzle) = (GPA x MPH x W) / 5,940
- GPM: Gallons per Minute
- GPA: Gallons per Acre
- MPH: Miles Per Hour
- W: Spray width (in inches) for single nozzle, band spraying, or boomless spraying
Example: Pre-emergence herbicide application with GPA = 20, MPH = 10, W = 20 inches banding width.
GPM = (20 GPA x 10 MPH x 20") / 5,940 = 0.67 GPM (Per Nozzle)
