Hi,

 

NFPA 13-2019 version clause 26.27.1.8. Fire pump room design density shall be 10.2 mm/min.

In a G+4 building fire pump room is located at basement. At fourth floor the furthest sprinkler design density is 6.1 l/min.

 

Question: In this case the hydraulic calculation of sprinkler shall be considered based on highest hazard i.e 10.2 mm/min from fire pump room or furthest sprinkler design density i.e 6.1 l/min at fourth floor?

 

Thanks in advance.

 

Regards,

Nirmal
