According to NFPA 13D, what is the required GPM for residential sprinklers?

• A. 12 GPM
• B. 15 GPM
• C. 18 GPM
• D. 20 GPM

Answer: (C)

The required flow rate for residential sprinklers according to NFPA 13D is 18 gallons per minute (GPM). This standard specifies that for a one- or two-family dwelling with a total area not exceeding 5,000 square feet, each sprinkler must be capable of discharging 18 GPM. This flow rate is designed to provide adequate water coverage for effective fire suppression in the types of occupancy stipulated by NFPA 13D, ensuring a sufficient level of safety for occupants and property. The specific requirement of 18 GPM reflects the standard's emphasis on balancing the effectiveness of sprinkler systems with practical considerations for residential applications.
