Q

Calculate the gpm fire flow of a tanker with 2,500 gallons of water and a travel and fill time of 10 minutes :

A

Capacity of 2,500 minus 20% (2,500 minus 500) = 2,000
2,000 divided by the 10-minute round trip = 200 gallons per minute

Q

Why is preplanning essential in areas without hydrants?

A

▪ The ability to build up and support these operations need to be identified early,
and additional resources need to be called for at that time.
▪ Build-up and support for this operation is time consuming and calls for an extremely
proactive approach by the initial IC.

A

The strainer floats on the surface of the water to draft from a static water source and does not need additional equipment to keep it
off the bottom of the water source.

78
Q

What is a turbo draft?

A

A device allows a unit to access a water supply that would normally be out of reach
when using a hard-suction hose. The turbo draft works off the venturi principle and the
unit is supplied by either a 2½-inch or 3-inch line with the return being LDH.

79
Q

What is an Automatic Air Primer?

A

Uses the venturi principal to evacuate air from
suction hoses and the pump by using the air supply from the apparatus onboard air tanks. When placed in the automatic mode, this device will allow for the primer to automatically begin
priming whenever the discharge pressure drops below 20 PSI.
