1. According to NFPA 1901, what is the minimum
pump capacity required for an apparatus to be
truly classified as a fire department pumper?
A) 500 GPM
B) 750 GPM
C) 1,000 GPM
D) 1,250 GPM
Answer: B) 750 GPM
Rationale: NFPA 1901 states that a standard fire
department pumper must have a minimum pump
capacity of 750 GPM (3 000 L/min) and a water
tank capacity of at least 300 gallons.
2. Which type of fire pump is most commonly
used as the main fire pump on modern fire
apparatus due to its ability to handle large
volumes of water efficiently?
,A) Rotary gear pump
B) Rotary vane pump
C) Centrifugal pump
D) Piston pump
Answer: C) Centrifugal pump
Rationale: Centrifugal pumps are the industry
standard for main pumps because they maximize
volume output, utilize incoming pressure, and
experience less mechanical wear compared to
positive-displacement pumps.
3. What role does a rotary vane pump typically
play in modern fire apparatus pumping systems?
A) Main fire pump
B) Auxiliary high-pressure pump
C) Priming pump
D) Foam concentrate injection pump
Answer: C) Priming pump
Rationale: Because centrifugal pumps cannot
pump air, a positive-displacement rotary vane
pump is used as a priming device to force air out
of the pump casing and draft water.
4. While drafting, if the pump operator changes
the transfer valve of a two-stage pump from
volume to pressure mode, what happens to the
internal flow?
A) Water flows through both impellers
simultaneously into the discharge.
B) Water enters the first impeller and is then directed
,into the eye of the second impeller.
C) The second impeller is completely bypassed to
save fuel.
D) Water is recirculated back to the tank to prevent
overheating.
Answer: B) Water enters the first impeller and is then
directed into the eye of the second impeller.
Rationale: In pressure (series) mode, the total
pressure is multiplied because the discharge of
the first stage feeds directly into the intake of the
second stage.
5. At what rated capacity percentage must a fire
pump be able to deliver its pump pressure at 150
psi net pump pressure during certification
testing?
A) 50%
B) 70%
C) 100%
D) 125%
Answer: C) 100%
Rationale: NFPA 1901 certification requires the
pump to deliver 100% of its rated capacity at 150
psi, 70% of capacity at 200 psi, and 50% of
capacity at 250 psi.
6. What is the fundamental formula used to
calculate Total Discharge Hydraulics (TPL) or
Total Pressure Loss in a hose lay?
, A) TPL = FL + AL + EP
B) TPL = NP + FL
C) TPL = FL - AL + EP
D) TPL = FL + NP - AL
Answer: A) TPL = FL + AL + EP
Rationale: Total Pressure Loss is the sum of
Friction Loss (FL), Appliance Loss (AL), and
Elevation Pressure (EP).
7. Calculate the friction loss in 200 feet of 2½-
inch hose flowing 250 GPM using the condensed
Q formula.
A) 12.5 psi
B) 25.0 psi
C) 31.2 psi
D) 50.0 psi
Answer: B) 25.0 psi
Rationale: The condensed Q formula for 2½-inch
hose is FL = Q². Since Q = = 2.5, FL =
2.5 × 2.5 = 6.25 psi per 100 feet. For 200 feet, 6.25
× 2 = 12.5 psi... Wait, let us recalculate: FL = Q²
per 100ft. Q=2.5. 2.5 * 2.5 = 6.25. For 200 ft, 6.25 *
2 = 12.5 psi. Let's correct the option choice
mentally; the true calculation yields 12.5 psi,
making A the correct answer.
8. An apparatus is supplying a nozzle located on
the 4th floor of a commercial building. What is
the elevation pressure loss for this setup?
