Multiple Choice

Doubling the pump pressure will double the nozzle output.

Explanation:
Doubling the pump pressure will not double nozzle output. For a fixed nozzle orifice, the flow rate increases with the square root of pressure, so doubling pressure raises flow by about sqrt(2) ≈ 1.41 times, not 2 times. In other words, going from 20 psi to 40 psi might increase output by roughly 41%, depending on the nozzle and system, but it won’t double. Higher pressure can also affect droplet size and drift, so pressure changes don’t translate to proportional changes in output.
