How is the spray application rate related to the sprayer’s application speed?

Explanation:
The spray application rate is determined by how much liquid is being emitted per unit time and how much area is covered per unit time. If the nozzle is delivering a constant flow and you move faster, you cover more area each minute, so the spray per acre goes down. Slow down and you put more spray onto each acre. The nozzle size (and pressure) change the flow rate itself, but with a fixed flow, the speed and rate per area move in the opposite direction. That’s why the relationship is inverse: faster speed means a lower gallons-per-acre rate, slower speed means a higher rate.
