A stored-pressure water-type fire extinguisher expels water in a solid stream with a range of _____.

• A. 15 to 20 feet
• B. 25 to 30 feet
• C. 35 to 40 feet
• D. 45 to 50 feet

Answer: (C)

The main concept here is how a stored‑pressure water extinguisher delivers its water and how that affects reach. Stored‑pressure water extinguishers emit a solid jet rather than a spray, because the water exits the nozzle in a focused stream driven by internal pressure. That solid stream preserves speed and coherence longer, so it travels farther before air resistance and gravity cause it to break up and fall. As a result, the typical horizontal reach for this type of extinguisher is in the mid‑range—about 35 to 40 feet. Shorter ranges would imply a weaker or more dispersed output, while much longer ranges aren’t characteristic of this nozzle design.
