If a sprayer applies 40 gallons per acre at 8 mph, what gallons per acre would be applied at 12 mph?

When the sprayer’s output (flow rate) is kept constant and the swath width stays the same, the gallons per acre is inversely related to speed. So if you move faster, you spend less time applying to each acre, and fewer gallons end up per acre.

From 8 mph to 12 mph, the application per acre scales by the ratio of speeds: 40 × (8/12) = 40 × 2/3 ≈ 26.7 gallons per acre. This matches the idea that increasing speed reduces gallons per acre when the system’s flow and setup aren’t changed.
