Certified Fire Protection Specialist (CFPS) — Question 5

In assessing the use of a sprinkler head with a Nominal K-Factor of 14.0, you find that this sprinkler head provides what percentage of the flow from a Nominal K-Factor 5.6 sprinkler device?

Answer options

• A. 100%
• B. 140%
• C. 250%
• D. 300%

Correct answer: D

Explanation

The correct answer is D, 300%, because the flow rate of a sprinkler is proportional to the square of its K-Factor. Therefore, (14.0^2) / (5.6^2) equals 300%. The other options are incorrect as they do not reflect the correct ratio of the flow rates based on the K-Factors provided.
