  1. What does the term 'K-factor' represent for a sprinkler head, and what are typical units used in the US?

    Answer: Discharge coefficient relating flow to pressure; measured in gpm/psi^0.5

    The K-factor is the discharge coefficient used in Q = K√P to calculate sprinkler flow, expressed in gpm/(psi)^0.5.

  2. Under NFPA 13, which pipe material requires the use of listed fittings and is NOT permitted for use in concealed spaces above certain temperatures without special listing?

    Answer: Chlorinated polyvinyl chloride (CPVC)

    CPVC plastic pipe is temperature-sensitive and requires special listings and precautions when used in concealed spaces exposed to elevated temperatures.

  3. A deluge system is most appropriate for which type of hazard?

    Answer: High-hazard areas where rapid fire spread is expected and all sprinklers must open simultaneously

    Deluge systems discharge water from all open sprinklers simultaneously, making them ideal for rapidly spreading, high-hazard fires such as aircraft hangars and flammable-liquid processes.

  4. What is the critical temperature at which structural steel loses approximately 50% of its yield strength?

    Answer: 1,000°F (538°C)

    Structural steel typically loses about 50% of its ambient-temperature yield strength when heated to approximately 1,000°F (538°C).

  5. In the context of NFPA 13 occupancy hazard classifications, which occupancy would be classified as 'Extra Hazard Group 2'?

    Answer: Flammable-liquid spray painting operation

    Extra Hazard Group 2 includes occupancies with flammable or combustible liquids in open processes such as spray painting.

  6. What is the primary purpose of listed fire-resistive joint systems at construction joints in fire-rated assemblies?

    Answer: To maintain the fire-resistance rating across the gap between rated assemblies

    Fire-resistive joint systems are tested and listed to maintain the fire-resistance rating across the movement gap between adjacent fire-rated assemblies.

  7. Under NFPA 20, what is the minimum net positive suction head available (NPSHa) requirement relative to the pump's NPSHR for a fire pump?

    Answer: NPSHa must exceed NPSHr at all flow rates through 150% of rated capacity

    NFPA 20 requires that the available NPSH exceed the required NPSH of the pump throughout its operating range, including at 150% of rated capacity.
