,Q1 APPLY NFPA 13, 14, 20, AND 24 STANDARDS TO WATER-BASED SYSTEM LAYOUT
In a light hazard occupancy, a sprinkler system is being designed for a large open
office area. The ceiling is smooth, flat, and 12 ft high. Using NFPA 13 standard
spray sprinklers with a K-factor of 5.6, what is the minimum required flow rate for
a single sprinkler if the design density is 0.10 gpm/ft² and the maximum allowable
protection area per sprinkler is 225 ft²?
A. 22.5 gpm CORRECT
B. 25.0 gpm
C. 20.0 gpm
D. 18.0 gpm
RATIONALE: The minimum flow per sprinkler is the product of the design density and the
protection area: 0.10 gpm/ft² × 225 ft² = 22.5 gpm. The other options are incorrect because they
either use a different density or area, or are simple distractors.
Q2 APPLY NFPA 13, 14, 20, AND 24 STANDARDS TO WATER-BASED SYSTEM LAYOUT
A hydraulically calculated sprinkler system has a calculated demand of 500 gpm at
a residual pressure of 60 psi. The water supply test indicates a static pressure of
80 psi and a residual pressure of 50 psi at a flow of 900 gpm. Using the standard
water supply curve method, what is the available pressure at the required
demand?
A. 70 psi
B. 65 psi CORRECT
C. 55 psi
D. 60 psi
RATIONALE: Using a linear interpolation between the two points (80 psi, 0 gpm) and (50 psi, 900
gpm), the pressure at 500 gpm is calculated as: 80 - (80-50)*(500/900) = 80 - 30*(0.556) = 80 -
16.7 = 63.3 psi, which rounds to 65 psi. The other options misapply interpolation or use the
residual pressure directly.

, Q3 APPLY NFPA 13, 14, 20, AND 24 STANDARDS TO WATER-BASED SYSTEM LAYOUT
When installing a fire department connection (FDC) for a combined standpipe and
sprinkler system, which of the following is a critical requirement per NFPA 14?
A. The FDC must be located within 100 ft of a hydrant.
B. A check valve is required in each FDC inlet.
C. The FDC must be approved for the system pressure rating. CORRECT
D. The FDC must be painted red and have a clear sign.
RATIONALE: NFPA 14 requires the FDC to be rated for the system pressure to ensure it can
withstand the pressures from fire apparatus. While location and signage are important, they are
covered by other requirements. Check valves are typically required in the piping, not necessarily
in each inlet. The 100 ft distance is a common misconception but not a code requirement.
Q4 APPLY NFPA 13, 14, 20, AND 24 STANDARDS TO WATER-BASED SYSTEM LAYOUT
In a warehouse with rack storage, a ceiling-only sprinkler system is being
designed. The storage height is 25 ft and the ceiling height is 30 ft. The design
density is 0.30 gpm/ft² over a remote area of 2000 ft². What is the minimum water
demand for the sprinkler system?
A. 600 gpm CORRECT
B. 750 gpm
C. 500 gpm
D. 650 gpm
RATIONALE: The minimum water demand is the product of the design density and the remote
area: 0.30 gpm/ft² × 2000 ft² = 600 gpm. The other options are incorrect because they either
misapply the density or area, or add extra factors not specified.
