The fire department connection in front of the high-rise is vandalized. How does the pump operator charge the standpipe system?
Charge the first floor standpipe connection
An apparatus and crew arrived on scene at a single-family dwelling, and there are evident fire conditions. Where does the pump operator locate the apparatus?
That position that offers tactical advantage
Which type of pump is used as a priming pump?
Rotary gear
Where is the advantage of stopping the apparatus short of the hydrant?
Allows the hose to curve preventing kinks

When operating a 6000 litre per minute pump, what is the maximum amount of time allowed to achieve prime?
45 seconds
What is a hydrant with the largest capacity connected to?
Primary feeder

Flow of water in litres per minute for a solid stream nozzle
What nozzle reaction does a 32 mm tip with 350 kPa nozzle pressure produce?
538 Newton’s
NR = 0.0015 x d² x NP
How is the transition made from the water tank to the external water supply?
Changing smoothly without interrupting the fire attack
When attack lines are used intermittently during pump operations, how does a pump operator ensure at the pump does not overheat?
Open the pump bypass valve
For drafting purposes, how is lift measured?
From the surface of the water to the pump intake
What is the procedure to increase the efficiency of water shuttle operations?
Decrease the time required to fill the tanker
When water suddenly stops moving through a hose, what is the result?
Water hammer
An apparatus is equipped with a 5,000 litre tank that supplies two preconnected hoselines; one flowing 600 litres per minute and the other flowing 400 litres per minute. How many minutes of agent applications are available?
5 minutes
While drafting and flowing water, a pump operator sees is a reading of -75 kPa on the compound gauge. What does this indicate?
The maximum vacuum capability is achieved
If the friction loss in 90 metres of hose is 490 kPa, what is the friction loss in 135 metres of the same size hose that is flowing the same amount of water?
735 kPa
What is the friction loss in 120 metres of 65 mm hose flowing 1200 litres per minute?
548 kPa
In a relay pumping operation, what is the purpose of the attack pumper?
Determine the required amount of water flow
In order to prevent damage during a relay operation, which apparatus initiates shutdown?
Attack pumper
What is the last apparatus to shut down in a relay operation?
Source Pumper
What is the formula for Friction Loss (FL)?
FL = C x Q² x L/100
What does C stand for in the FL formula?
Fricion loss coefficient based on hose diameter
What does Q stand for in the FL formula?
Flow rate in hundreds of litres per minute (lpm/100)
What does L stand for in the FL formula?
Hose length in hundreds of metres (metres/100)
What is the FL coefficient for 38mm hose?
38
What is the FL coefficient for 45mm hose?
24.6
What is the FL coefficient for 65mm hose?
3.17
What is the formula to determine water flow from a smooth bore nozzle?
L/min = .067xd²x√NP
When the intake pressure Falls below 140 kPa during relay pumping what does that signal?
There is danger of cavitation
What is the principle that causes foam concentrate to move through an inline foam eductor and into the water stream?
Venturi
What factors are considered When selecting a foam proportioner?
Required ratio of foam in length and size of a attack line
The nozzle crew indicates there is not enough foam at the nozzle how does the pump operator correct this problem?
Add additional foam concentrate
Pump operator, using an in-line eductor, notices the phone being generated is of poor quality. What is the reason for his failure?
Flow through the eductor exceeds its rated capacity
When pumping to an automatic standpipe system what friction loss does a pump operator allow?
35 kPa
