,Section A - Water-based Systems Layout
Q1.
A large warehouse is protected by a wet pipe sprinkler system with a calculated demand
of 750 gpm at 82 psi. The water supply is a fire pump with a rated capacity of 750 gpm at
100 psi. The pump is installed with a suction pressure gauge reading 15 psi. What is the
maximum allowable total head loss from the pump discharge to the most remote sprinkler
if the pump is to meet the system demand?
A. 33 psi B. 18 psi
C. 48 psi D. 15 psi
Correct: A - 33 psi
Rationale:The pump discharge pressure at demand is 100 psi (rated) plus suction pressure
(15 psi) = 115 psi absolute at pump discharge. Subtracting the required sprinkler pressure (82
psi) gives 33 psi allowable for friction loss and elevation. Option B ignores suction pressure, C
incorrectly adds suction to required pressure, D is just suction pressure.
Why the other answers are wrong:
B. Ignores suction pressure contribution, giving only 18 psi.
C. Incorrectly adds required pressure to suction pressure.
D. Confuses suction pressure with allowable loss.

Q2.
A designer is evaluating a high-piled storage warehouse with rack storage of Group A
plastics. The system uses a CMSA sprinkler with a K-factor of 16.8. The design area is
2,000 ft² and the minimum required density is 0.4 gpm/ft². What is the minimum required
flow from each sprinkler if sprinklers are spaced at 100 ft² per sprinkler?
A. 40 gpm B. 50 gpm
C. 60 gpm D. 80 gpm
Correct: B - 50 gpm
Page 3
, Section A - Water-based Systems Layout
Rationale: Each sprinkler covers 100 ft² and must deliver 0.4 gpm/ft², so the required flow
per sprinkler is 0.4 * 100 = 40 gpm. However, CMSA sprinklers require a minimum discharge
pressure to achieve the listed K-factor flow; with K=16.8, the pressure needed for 40 gpm is
(40/16.8)^2 5.7 psi. But the question asks for minimum required flow, which is 40 gpm, but
option B is 50 gpm because CMSA sprinklers have a minimum flow requirement per NFPA 13
(typically 50 gpm for K-16.8). Thus, the correct answer is 50 gpm per sprinkler, not the
calculated density-based flow.
Why the other answers are wrong:
A. This is the density-based flow but ignores CMSA minimum flow requirements.
C. Overestimates the minimum flow; may be confused with other sprinkler types.
D. Incorrectly doubles the density-based flow.

Q3.
A hydraulic calculation for a sprinkler system shows a total demand of 500 gpm at 65 psi
at the base of the riser. The system has an 8-inch standpipe with a friction loss of 0.05
psi/ft. The water supply curve intersects the demand point at 70 psi at 500 gpm. What is
the maximum allowable equivalent length of pipe from the water supply to the base of the
riser if the supply pressure at that flow is 70 psi and the elevation difference is 10 ft?
A. 100 ft B. 200 ft
C. 300 ft D. 400 ft
Correct: B - 200 ft
