Frequently asked questions

How does nozzle flow change with pressure?
Nozzle flow scales with the square root of pressure: Q = Qr·√(P/Pr). Doubling the pressure raises flow by about 41%, so a small pressure change moves the application rate noticeably.
What is the broadcast application rate formula?
GPA = 5940 · Q / (S · W), where Q is gpm per nozzle, S is travel speed in mph and W is nozzle spacing in inches. The 5940 constant folds the acre, mile and minute unit conversions.
How high should a spray boom run?
Set boom height for a 30% double overlap: H = S·(1−0.30) / (2·tan(θ/2)), where S is nozzle spacing and θ is the full fan angle. Too low and the pattern streaks; too high and drift and overlap increase.
