How does a FPE calculate the fire water demand for a building? For example, a Light Hazard building with 3200 s.f. Using a wet-pipe system and Density/Area Curves in NFPA 13, I'm coming up with 150 gpm (0.10*1500) as a minimum water demand for this building. Assuming hose streams are not required for this example.
Is it safe to tell a FPE to design a sprinkler system for this building using 150 gpm and not go over this number as the pressure at the higher flow is too low? I'm guessing that the FPE would use a computer program such as Haas or something to run the numbers. Does Haas has its own way to calculate water demand for the building?
I have seen a submitted hydraulic calculations where the sprinkler flow is 375.91 gpm for the building using 0.10 gpm/s.f. Not quite sure why the flow is so high and if it's possible to lower the flow.
Thanks.
