2. What does One cubic foot of water contain in inches? - ANSWER 1.728
cubic inches
3. What does One cubic foot of water contain in gallons? - ANSWER 7.5
gallons
4. What does One gallon of water weigh? - ANSWER 8.35 lbs
5. What is Newton's Third Law of motion pertaining to Nozzle Reaction? -
ANSWER "For every action there is an equal and opposite reaction"
6. What are the two variables that affect the reach of fire streams? - ANSWER
1. Air Resistance
2. Gravity
7. What angle does a stream get the greatest horizontal reach? - ANSWER 30-
34 degrees
8. What angle does a stream get the maximum effective vertical reach? -
ANSWER 60-75 degrees
,9. What percent can head and tail winds affect the reach of a stream? -
ANSWER 10% to 15%
10.What is Q value for the Q formula - ANSWER Q= GPM divided by 100
Example: 200 GPM=2.00
Q=2
11.How do you Calculate Elevation? - ANSWER Add 5 psi for each floor of
elevation (exclude 1st floor)
Subtract 5 psi for each floor below grade
12.What is the pressure for Standpipe system and siamese? - ANSWER add 25
psi
13.What is the pressure for Gated Wye's and Siamese appliances? - ANSWER
Add 10 psi
14.What psi should be provided to Sprinkler Systems? - ANSWER Sprinkler
Systems shall be maintained at 150 psi pump discharge pressures
15.What is RED LINE? - ANSWER The Point at which the decision should be
made to either add a line to help deliver the desire GPM or to use a larger
sized line. Any time the GPM desired produces a friction loss of
approximately 36 psi per 100 feet of hose, the "Red Line" has been reached.

without assistance.
Cognitive - ANSWER Cognitive
19.Engine/Auxiliary coolers permits water from pump to cool radiator water by
means of a heat exchanger - ANSWER Cooling Devices
20.The difference between static and residual pressures as found on the
compound gauge. - ANSWER Drop
21.Two pumpers connected independently to the same fire hydrant. -
ANSWER Dual Pumping
22.Used primarily on portable pumps where the velocity of exhaust gases
passing through a venturi creates a vacuum. Require High engine RPM and
is not very efficient. - ANSWER Exhaust Primers
23.What does One gallon of water contain in inches? - ANSWER 231 cubic
inches
24.How high will One psi elevate water? - ANSWER 2.304 feet
25.What is atmospheric pressure at sea level? - ANSWER 14.7 psi
26.What is the maximum lift for drafting? (Theoretically) - ANSWER 34 feet
