What is the minimum required flow rate in gallons per minute (gpm) for a residential sprinkler head under NFPA 13D?

Accepted Answer

13 gpm

Answer

NFPA 13D requires a minimum flow of 13 gpm per sprinkler head for residential applications to control fires in one- and two-family dwellings.

Question 2

Which extinguishing agent is most appropriate for suppressing a three-dimensional flowing fuel fire?

Accepted Answer

Heat and flame passage for a specified time period

Question 4

The 'water supply available pressure' for sprinkler system design is typically determined by which method?

Accepted Answer

A fire flow test at a nearby hydrant

Answer

A hydrant flow test measures static pressure, residual pressure, and flow rate to establish the actual available water supply for sprinkler design.

Question 5
