What is the primary purpose of a fire department water supply System?

Provide adequate quantity of water for fire suppression

100
A connection point firefighters use to obtain water from a municipal water system.

Fire Hydrant

100

What are the pipes that carry water throughout a municipal water distribution system called

Water Mains
100

This apparatus transports large amount water to fires where hydrants are unavailable.

Water tanker (tender)

100

This pressure exists in a water system when no water is flowing

Static

200
Water supplied to a community by a city through a network of pipes is known as what type of system? 

Municipal water system

200
Which type of hydrant normally has water in its barrel at all times

Wet Barrel 

200

This type of water main is supplied from only one direction

Dead end system

200
This portable piece of equipment is set up to hold water delivered by tankers/ tenders during rural operations

Portable Water Tank

200

Pressure is measured while water is flowing from the system

Residual pressure

300

Lakes, ponds, rivers, and streams are examples of what type of water source?

Static water source

300

What type of hydrant design keeps water below ground until the main valve is opened. 

Dry-Barrel

300

This distribution arrangement allows water to reach a hydrant from more than one direction.

Grid system

300

This operation uses multiple water tanker/tenders traveling between a fill site and a fire scene

Water Shuttle operation

300

During a hydrant flow test this pressure is measured at the flowing hydrant outlet

Pitot

400

What is the term that describes the amount of water moving past a point during a specific period of time?

Flow

400

How many GPM can a firefighter expect to get out of a hydrant that has a bonnet (top) that is painted green?

1000-1499

400

Compared to a grid system this type of main arrangement is more likely to experience reduced flow.

Dead end main

400

This operation uses a pump to obtain water from a static source such as a pond or lake

Drafting

400

Tool used to measure the pressure of water flowing from a hydrant outlet.

Pitot guage

500
What is the unit of measurement used by the fire service to measure water flow

Gallons Per Minute GPM

500

After closing a dry barrel hydrant, firefighters should verify that this process has occurred.

Draining

500

These devices control section of municipal water distribution systems and allow portions to be shut down for maintenance or emergencies.

Control Valves
500

A device that is attached to the end of a hard suction hose to prevent debris from entering the pump during drafting 

Strainer

500

In the hydrant-flow formula, this factor accounts for the shape and condition of the hydrant outlet
