[All CFPE Questions]

Exhibit.

The automatic fire sprinkler system remote area located on plan F2.0 indicates that the fire sprinkler system has been designed to deliver

A20 gpm ( 76 L/mm) over 2 000 tt2 (186 m2)

B15 gpm ( 57 L/min) over 1 500 ft2 (139 m2)

C10 gpm ( 38 L/min) over 1 500 tt2 (139 m2)

D20 gpm ( 76 L/min) over 1 500 ft2 (139 m2)

Show Suggested Answer

Suggested Answer: A

In sprinkler design, the 'remote area' refers to the section of a building that is most challenging to protect with sprinklers due to its location and characteristics. The design criteria usually specify the minimum density of water (gallons per minute per square foot or liters per minute per square meter) over a specified area that the system must deliver. Based on the standard requirements for typical commercial occupancies, a delivery rate of 15 gpm (57 L/min) over 1,500 ft (139 m) is common for light to ordinary hazard classifications.

20 gpm over 2,000 ft²? That seems a bit high, doesn't it?

I vaguely remember that 10 gpm is often the minimum, but I’m not confident about the area it covers.

I feel like option D makes sense since it matches the 20 gpm with a smaller area, but I can't recall the exact requirements.

I think I practiced a similar question where the required flow was 15 gpm over a larger area. This one seems tricky!

I remember studying the flow rates for different sprinkler systems, but I'm not sure if 20 gpm is too high for 1,500 ft².

I feel pretty confident about this. The exhibit provides the necessary details, and I know the typical design requirements for fire sprinkler systems. I'll review the choices and select the one that best matches the information given.

This is a tricky one. There are a lot of numbers and units to keep track of. I'll need to take my time and double-check my work to make sure I don't miss anything important.

Okay, I think I've got this. The key is to identify the design parameters, like the required flow rate and coverage area. I'll carefully compare the answer choices to the information in the exhibit to find the right match.

Hmm, I'm a bit unsure about this one. The exhibit shows some technical details, but I'm not sure I fully understand the requirements for the fire sprinkler system. I'll need to think this through step-by-step.

Hmm, I'm going to have to go with C on this one. 10 gpm (38 L/min) over 1,500 ft2 (139 m2) seems a bit low, but hey, you never know!
