QUESTIONS AND SOLUTIONS
CERTIFICATION EVALUATION GRADED A+
⩥ Dry-Barrel Hydrant.
Answer: Fire hydrant that has its operating valve located at the base or
foot of the hydrant rather than in the barrel of the hydrant. When
operating properly, there is no water in the barrel of the hydrant when it
is not in use. These hydrants are used in areas where freezing may occur.
⩥ Elevation pressure.
Answer: The amount of pressure created by gravity
⩥ Flow pressure.
Answer: Forward pressure at a discharge opening while water is
flowing.
⩥ Hardness.
Answer: Mineral content of water, usually consisting of calcium and
magnesium.
⩥ heat of vaporization.
,Answer: The amount of energy required for the liquid at its boiling point
to become a gas
⩥ kinetic energy.
Answer: the energy an object has due to its motion
⩥ Normal operating pressure.
Answer: The observed static pressure in a water distribution system
during a period of normal demand.
⩥ Pitot gauge.
Answer: A type of gauge that is used to measure the velocity pressure of
water that is being discharged from an opening. It is used to determine
the flow of water from a hydrant.
⩥ potential energy.
Answer: stored energy that results from the position or shape of an
object
⩥ Residual pressure.
Answer: The pressure that exists in the distribution system, measured at
the residual hydrant at the time the flow readings are taken at the flow
hydrants.
,⩥ specific heat index.
Answer: The amount of heat energy required to raise the temperature of
a substance. These values are determined experimentally and then made
available in tabular form.
⩥ surface tension.
Answer: Elastic like force at the surface of a liquid, which tends to
minimize the surface area, causing water droplets to form
⩥ Turbidity.
Answer: Amount of suspended particles in water
⩥ How often should dry hydrants be flow-tested?.
Answer: Annually
⩥ Class C fire hydrant color and flow.
Answer: Red; less than 500 gpm
⩥ A Class B hydrant has a flow rate of ___________ gallons per minute.
Color?.
Answer: 500 to 999 gpm; orange
⩥ CLASS A HYDRANT COLOR AND GPM.
, Answer: Green, 1000-1499 GPM
⩥ Class AA Hydrant.
Answer: 1 500 gpm (5 680 L/min) or greater. Light blue top and nozzles.
⩥ Which way should the fire hydrant connections, especially the large
steamer connection, be facing?.
Answer: Towards the street
⩥ How much clearance does NFPA 291 require the center of a hose
outlet on a fire hydrant be from the finish grade surface?.
Answer: A minimum of 8 inches
⩥ How can you tell if a dry-barrel hydrant is fully drained before
replacing caps?.
Answer: Placing a hand over the outlet, if you feel suction, the hydrant
has not finished draining
⩥ How far are fire hydrants placed apart?.
Answer: About 500 ft in residential areas and about 300 ft in high value
commercial or industrial areas
⩥ True or false; you should always fully open and fully close a dry
barrel hydrant..
