Piercing Nozzle flow at 50 psi is:

Piercing Nozzle flow at 50 psi is:

• A. 150 gpm @ 50 psi
• B. 300 gpm @ 50 psi
• C. 100 gpm @ 60 psi
• D. 200 gpm @ 60 psi

Answer: (A)

Piercing nozzles have a fixed flow rating at a standard nozzle pressure. For this nozzle, the published rating is about 150 gpm when operated at 50 psi at the nozzle. That makes 150 gpm at 50 psi the correct match. The other options don’t fit because they pair flows with pressures that aren’t the nozzle’s rated combination. A piercing nozzle isn’t expected to deliver 300 gpm at 50 psi, and the 60 psi options don’t align with the 50 psi rating. In practice, you use the nozzle’s specified rating at the standard pressure rather than applying a simple pressure-to-flow rule.
