PKP extinguisher ranges increase with heavier weight: 18 lbs yields about 19 ft, 27 lbs yields about 21 ft. Which statement best describes this relationship?

PKP extinguisher ranges increase with heavier weight: 18 lbs yields about 19 ft, 27 lbs yields about 21 ft. Which statement best describes this relationship?

• A. It decreases with weight
• B. It stays constant
• C. It increases with weight
• D. It is not determined by weight

Answer: (C)

The concept being tested is how the amount of extinguishing agent (weight) relates to how far the discharge can reach. For PKP extinguishers, a heavier unit carries more agent and often maintains the discharge energy long enough to push the stream farther. The given data show 18 pounds projecting about 19 feet and 27 pounds about 21 feet, indicating a clear positive relationship: as weight increases, range increases. In this context, more mass behind the jet means more momentum and a longer projection before the agent is exhausted. So the best description is that the range increases with weight.
