Increasing pressure to compensate for a wrong nozzle size tends to cause what?

Explanation:
Raising system pressure to compensate for a nozzle that's too small increases the velocity and atomization of the spray, which produces a higher proportion of fine droplets that drift more easily with the wind. At the same time, the higher pressure causes more abrasive wear on the nozzle and seals, accelerating wear and potentially shortening nozzle life. So the result is more drift and more wear, not better control or longer nozzle life.
