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

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

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!

User1: I think C is too low, I'm going with A. 20 gpm (76 L/min) over 2,000 ft2 (186 m2) seems more reasonable.

B seems like the right choice to me. 15 gpm (57 L/min) over 1,500 ft2 (139 m2) sounds about right for a standard sprinkler system.

I agree with Lelia, because a larger area would require more water flow to cover it effectively.
