APPENDIX 8 CALCULATING THE
CALIBRATION VALUES
SECTION WIDTHS
Use the following formulas to help calculate the boom or implement section widths for either broadcast or band
applications.
BROADCAST
Calculate the section width with the formula:
Where T = the number of Tips in each section, S = the Spacing between tips, and SW = the Section Width.
FOR EXAMPLE:
20 tips in a section with spacing of 40 inches would yield:
or a Section Width of 800 inches (approximately 67 feet). Enter 800 as the width for this section.
BAND
To calculate the adjusted applied rate for band spraying applications, use the following formula:
Where BR = the Broadcast Rate, BW = the Band Width, S = the Spacing between the tips, and AR = the Adjusted
Rate for band spraying.
FOR EXAMPLE:
If the broadcast rate is 20 GPA, the band width is 14 inches, and the tip spacing is 40 inches:
Therefore, the adjusted rate is 7 GPA.
RATE CAL
The following information must be known in order to determine which spray nozzles to use with the sprayer.
• Nominal Application Pressure_________ PSI [kpa]
• Target Application Rate_________ GPA [lit/ha]
• Target Speed_________ MPH [km/h]
