Which variable is not directly used in the provided GPM calculation?

Explanation:
GPM is determined by how much water you need per area and how fast and wide you’re applying it. The gallons-per-acre rate tells you the water per unit area, while miles per hour (speed) and the spray width (how wide each pass is) set how much area you cover over time; multiplying those together converts area-per-minute into the gallons-per-minute you must deliver. Temperature doesn’t enter this direct calculation; it can influence spray behavior—like droplet size or evaporation—but the basic GPM math uses GPA, MPH, and width, not temperature.
