7. DETERMINE APPLICATION RATE
A. Choose a desired ground speed within factory recommended range of 5 to 8 miles per hour (mph).
B. By knowing tip size and desired ground speed, refer to English or Metric Application Rate Chart
(shown on following pages to determine application rate (US gallons per acre or liters per hectare)
based on different operation pressures.
C. Example of how to obtain 5.0 U.S. gallons per acre application rate:
1. Determined tip size to be XR8001.
2. Choose desired ground speed to be 6 miles per hour (mph).
3. Refer to English Application Rate Chart (shown on following page) to see that XR8001 tip trav-
eling at 6 mph will deliver 5.0 U.S. gallons per acre at 40 psi operation pressure.
D. Spraying solutions other than water: All tabulations in this manual are based on spraying water
which weighs 8.34 lbs. per U.S. gallon. Conversion factors must be used when spraying solutions
which are heavier or lighter than water. To properly size nozzles for the solution to be sprayed
multiply the desired GPM or GPA of solution by the water rate conversion factor, then use the new
converted GPM or GPA rate to select the proper size nozzle.
Example: Desired application rate is 20GPA of 28%N. Determine the correct nozzle size as fol-
lows:
GPA (solution) x Conversion factor = GPA (from table)
20GPA (28%) x 1.13 = 22.6 GPA (water)
The applicator should choose a nozzle size that will supply 22.6 GPA of water at the desired pres-
sure.
