(19 cards)
conventional engine apparatus in the FD are how many GPM and max pressure of what
2000 GPM
max pressure 600 psi
which engines have two stage 2000 GPM pumps
high pressure engines
600 psi
3rd stage engines have a total capacity of how many GPM and max pressure of
2000 GOM max pressure rating 700 psi
what is the default setting for fdny engine apparatus
Volume
what reasons would an engine have to operate on pressure
supplying a standpipe in a high rise building
the idle pressure when in pressure operation is roughly
110 psi
pressure operation should only be used when head pressure must be overcome, such as
supplying a FD connection for a standpipe system
booster tank is how many gallons
500
when the deck pipe 1 1/2 tip is used it will flow roughly
660 gpm with 100 psi at the tip
when the deck pipe 2 inch tip is used it will flow roughly
840 gpm with 50 at the tip
when is the max rated flow of 2000 gpm reached on the deck pipe
when the 2 1/2 tip is supplied with 116 psi
when a hose bed contains 1 3/4 the first 6 lengths must be
1 3/4 no more no fee than 6 lengths are permissible
how many folds of hose in the bed is roughly one 50’ length
4 folds
each horseshoe should be comprised of at least
one 50’ length
how many lengths of 2” lightweight house shall be maintained on an engine with a nozzle
1 length required
how many lengths of 2 1/2 lightweight hose shall be kept on engine
3 lengths (one with nozzle)
how is the 2” lightweight hose distinguished
green with a red stripe
how is the 2 1/2 lightweight hose distinguished
white with a red strip
based on local hydrant pressure the master gauge will range from
150 to 210 psi
