How does droplet size impact drift potential?

Explanation:
Droplet size directly affects how long droplets stay in the air and how far air movement can carry them. Larger droplets are heavier, so they settle toward the ground more quickly (higher settling velocity) and don’t travel far as drift. Smaller droplets are lighter and have lower settling velocity, making them easier for wind and turbulence to carry away from the target. So, as droplet size increases, drift potential decreases, meaning larger droplets travel less.
