What does one 62.5 lbs
cubic foot of
water weigh?
What does One 1.728 cubic inches
cubic foot of
water contain in
inches?
,What does One 7.5 gallons
cubic foot of
water contain in
gallons?
What does One 8.35 lbs
gallon of water
weigh?
What does One 231 cubic inches
gallon of water
contain in
inches?
What is One foot .434 psi
of water exert as
a back pressure?
How high will 2.304 feet
One psi elevate
water?
What is 14.7 psi
atmospheric
pressure at sea
level?
,What is the 34 feet
maximum lift for
drafting?
(Theoretically)
How high does 1.13 feet of lift
One inch (1")
mercury (inches
in vacuum) lift?
What is the 10 psi
recommended
minimum psi that
should be
maintained on
the compound
gauge when
taking water
from a hydrant?
Stored or potential energy that is
What is Static available to force water through
pressure? pipes and fittings, fire hose, and
adapters.
, That part of the total pressure that is
not used to overcome friction or
Residual
gravity while forcing water through
Pressure
fire hose, pipe, fittings, and
adapters.
Take Static pressure and subtracting
residual pressure which gets you
How to calculate your drop. Take your drop and
psi loss for each multiply it by (2)² for second line,
additional line (3)² for third line, (4)² for forth line,
off hydrant and (5)² for fifth line. so long as after you
know how many multiply drop and the multiplayer for
lines can be the number line and still have 10 psi
taken off left based off static pressure you
hydrant? can have that many lines if you have
less than 10 psi you can not operate
that number of lines.
Example: Static pressure: 65 psi
Residual pressure : 60 psi
Examples of how
Drop: 5 psi
to calculate psi
2nd line: 2²=4: 4x5= 20
loss for each
3rd line: 3²=9: 9x5= 45
additional line
4th line: 4²=16: 16x5= 80 This line
off hydrant
can't be done because it is over 65
psi
