At the same GPM, which statement about nozzle pressures is true?

Explanation:
At a given flow rate, the pressure at the nozzle depends on how the nozzle produces the spray. Fog nozzles atomize water into a fine mist by forcing it through restrictive passages and shear processes, which adds resistance and requires more energy. Smooth-bore nozzles deliver water as a relatively coherent jet with fewer internal losses, so the same volume can exit at a lower pressure. Therefore, for the same GPM, fog nozzles operate at higher nozzle pressures than smooth-bore nozzles.
