FAE (FIRE APPARATUS ENGINEER)
ILLINOIS EXAM WITH 2024-2025
VERIFIED ANSWERS AND CORRECT
QUESTIONS GRADED A+
62.5 lbs - ANS-What does one cubic foot of water weigh?
1.728 cubic inches - ANS-What does One cubic foot of water contain in inches?
7.5 gallons - ANS-What does One cubic foot of water contain in gallons?
8.35 lbs - ANS-What does One gallon of water weigh?
231 cubic inches - ANS-What does One gallon of water contain in inches?
.434 psi - ANS-What is One foot of water exert as a back pressure?
,2.304 feet - ANS-How high will One psi elevate water?
14.7 psi - ANS-What is atmospheric pressure at sea level?
34 feet - ANS-What is the maximum lift for drafting? (Theoretically)
1.13 feet of lift - ANS-How high does One inch (1") mercury (inches in vacuum) lift?
10 psi - ANS-What is the recommended minimum psi that should be maintained on the compound
gauge when taking water from a hydrant?
Stored or potential energy that is available to force water through pipes and fittings, fire hose, and
adapters. - ANS-What is Static pressure?
That part of the total pressure that is not used to overcome friction or gravity while forcing water
through fire hose, pipe, fittings, and adapters. - ANS-Residual Pressure
Take Static pressure and subtracting residual pressure which gets you your drop. Take your drop and
multiply it by (2)² for second line, (3)² for third line, (4)² for forth line, (5)² for fifth line. so long as after
you multiply drop and the multiplayer for the number line and still have 10 psi left based off static
pressure you can have that many lines if you have less than 10 psi you can not operate that number of
lines. - ANS-How to calculate psi loss for each additional line off hydrant and know how many lines can
be taken off hydrant?
4th line: 4²=16: 16x5= 80 This line can't be done because it is over 65 psi - ANS-Examples of how to
calculate psi loss for each additional line off hydrant
1. 2 Hour: 100% @ 150 psi
, 2. 1/2 hour: 70% @ 200 psi
3. 1/2 hour: 50% @ 250 psi
4. 10 minutes: 100% @ 165 psi (overload or spurt test) - ANS-What are all the steps in Certification Test
(pre-service tests)?
100% @ 165 psi (done in certification test for 10 minutes) - ANS-What is a Spurt or Overload test?
1. 20 minutes: 100% @ 150 psi
2. 10 minutes: 70 % @ 200 psi
3. 10 minutes: 50% @ 250 psi
Optional: 100% @ 165 psi (overload or spurt test) - ANS-What are all the steps in a Service Test?
100% capacity @ 150 psi net pump pressure
70% capacity @ 200 psi net pump pressure
50% capacity @ 250 psi net pump pressure - ANS-What are Pump Tests?
Net Pump Pressure (NEP) is the measurement of the total work performed by the pump:
a. To lift water into the pump (drafting)
b. To discharge water from the pump
NEP= Suction Side Work(drafting) + Discharge Side Work - ANS-What is Net Engine/Pump Pressure
(NEP)?
Examples:
Discharge gauge reads 165 psi but you are getting supplied by hydrant @ 65 psi on your intake gauge. So
the net pressure would only be 100 psi.
Now your are drafting and Intake gauge reads 20" mercury (-20) and Discharge reads 120 psi. So your
net pump pressure is 140 - ANS-Examples of figuring out Net Engine/Pump Pressure (NEP)
Pump Discharge Pressure (PDP) is:
PDP= Net pump pressure(NEP) - Suction Side Work - ANS-What is Pump Discharge Pressure?
