cylinder that is 1 ft tall?
1 = 150 3 with 2 1/2 couplings = 0.8
1:1 When transferring the power from the rear axle to a fire
pump, what is the typical gear ratio?
,1 1/2 A collapse zone is a distance of _____________________ times the
height of the building in which fire fighters and fire apparatus
must not be located in case of a building collapse.
1 1/2 = 24 3 with 3 couplings = 0.67
1/2 Water a 32 degrees Fahrenheit is almost ________________ pounds
per cubic foot heavier than water at 100 degrees Fahrenheit.
1 3/4 = 15.5 3 1/2 = .34
1 minute In accordance with NFPA 1901, a fire apparatus wiht a
completely discharged air system must be able to move
within _________________ of start up.

level? NFPA 1002: 10.2.1, 10.2.1(A)
A. 3.1417 psi (22 kPa) Page: 324
B. 7.69 psi (53 kPa)

2 Ten degrees of play is equivalent to ___________ inches of
movement at the rim of a 20-inch steering wheel.
2 What is the minimum number of 2.5 inch discharge outlets
required for a pump rated at 750 gallons per minute or
greater.
2= 8 4 = .2
, 2.5 inch Which size of medium- diameter fire hose is most often used
for heavy interior attack lines?
2.5 inch attack hose Generally considered to deliver a flow rate of 250 gpm. It
takes at least two firefighters to safely control this size of
handline owing to the combined weight of the hose and the
nozzle reaction force.
2.31; 9.812 To determine the head pressure, divide the height of the
column in feet by _________ (metric = height in meters divided
by ___________).
2 mi/h When the fire apparatus is designed for pump-and-roll
operations, the fire apparatus engine and drive train must be
arranged so that the unit can pump at least 20 gpm at a
gauge pressure of 80 psi while the fire apparatus is moving
at a speed of:
2 minutes If the fire apparatus engine does not start within 30 seconds
after the starter has been engaged release the starter switch
and allow the starter motor to cool for __________________ before
attempting to start it again.
