What will doubling the ground speed of a sprayer do if nozzle pressure remains constant?

Explanation:
Doubling the ground speed while keeping nozzle pressure (and thus flow) constant reduces the spray volume applied per acre. With the same flow rate from the nozzles, you cover more acres each minute when you go faster, so the liquid per acre drops in proportion to the speed increase. If speed doubles, gallons per acre becomes about half. This is why maintaining the same GPA requires increasing flow (higher pressure or larger nozzles) when speed goes up.
