- Keep every value in the unit shown beside its field.
- Select Calculate and review each result and assumption.
- Verify important decisions with local records, labels, extension guidance, or a qualified adviser.
Formula and method
GPA = 5,940 × nozzle flow (GPM) ÷ [speed (mph) × nozzle spacing (in)].
The standard broadcast-sprayer relationship calculates application volume and tank coverage.
Worked example
At 0.3 GPM, 5 mph and 20-inch spacing, output is 17.82 GPA and a 500-gallon tank covers about 28.1 acres.
Understanding the result
Treat the calculated values as a planning estimate. Compare them with your field records, product information, local conditions and operational capacity before acting.
Important: Calibrate with clean water and verify nozzle uniformity, label requirements, PPE and local rules.
