Q

A _____ determines whether the pump will be operated in series/pressure mode or parallel/volume mode

A

Transfer valve

24
Q

When more than 50 percent of the pumps rated capacity is needed on the fire ground, the pump should be operated in ______ to ensure that the desired flow can be achieved

A

Parallel/volume mode

25
Q

Is the position in which two stage pumps are most commonly operated

A

Series/pressure mode

26
Q

Most fire responses do not require the pump to deliver more than 50 percent of the pumps rated capacity. Therefore, the pump is left in _______ so that the desired pressure is achieved by operating at a lower rate

A

Series pressure mode

27
Q

If the pump operation requires a large volume of water, then the pump should be operated in ______

A

Parallel volume mode

28
Q

The _____ of the pump is where the water enters the pump

A

Intake side

29
Q

The location where the water exists the pump is called the _____

A

Discharge side

30
Q

The pipe that leads from the apparatus water tank to the fire pump is commonly referred to as the _____

A

Tank to pump

31
Q

The tank to pump piping also contains a ______ which allows water to flow only from the tank into the pump and not back inside the tank

A

Check valve

32
Q

Most common intake connections are national standard thread or sexless type connections, such as a _________

A

Storz connector

33
Q

Each intake valve that has a connection larger than 3 inches must be equipped with an adjustable _______ installed on the supply intake of the valve to bleed off excess pressure coming into the valve.

A

Automatic intake pressure relief valve

34
Q

Each intake valve must also be equipped with a ______ to remove any air trapped in a hose before it enters the centrifugal fire pump

A

Bleeder valve

35
