Now lei Us pry into the practical principles
which govern the construction of walter works
A. laid down in treatise on hydraulics. The
grea' object Ia accomplish is tO get sufficient
pressure on the hydranls. This is the sine qua
OF the whole enterprise. If protection against
fire Is expected. Frr to JET quaniity ot water
to certain height or h,rZonlal distance, there
wafer at The plug hole Of the hy,lrant. This
pressure is derived in one OF two ways either hy
The weight Of a column of water acting vertically
or bv the pressure OF Il pumps piston pushing n
column of water against the plug hole Thr
pressure oi wafer occa>ioued by gravity in a
pipe ten miles long with one end elevated ten
ieet above the o. her end, lis base, would press on
its base, per square inch, just the same as pipe
only ten feet long of like or different bore Set
vertically would press per square inch its
base. Hence ii is the vertical height only that
produces the weight or pressure Of water. And
since u column ot water one foot high on base
of he square inch is found TO weigh or press 434
OF pOuud-less than halt pound per loot of
aIiitude-ihe pressure OF any column ou Il square
inch is readily found by multiplying the height
vi the column by 434 For example, the pres
sure of column ut waller 92 feet high per
square inch, is 90 x434, equal To 40 pounds, ami
TIN, is the pressure We will adopt in figuring
the hydrants OF Tallahassee, az we can hardly
get d tank elevated much higher. The eeva-
tIon OF the upper surface of u column of water
above any level plane below is technically called
the head ut water above That plane and may be
estimated either in feet ar pounds. As for ex-
ample, we say head of 100 feet or u pres
sure OF ABA pounds, and express the ,ne tOrce
rs is convertible into the other. II N ,tIers
not in the calculations whether column of
water produce the pressures or they trans
mltled from steam pump but il may be seen
that column of water has To reach very high
to comp te with the force of steam pump
For example, one hundred pounds of effective
team pressure equals the effective pressure of a
column OF water $50 feet high, both bearing on
equal bases From This you can perceive how
far more effective steam pump is than any
standpipc tank OF the ordinary height of one hun
dred feet.
Water passing through pipes or hose meets
with a resistance, commonly called friction,
which is the paramount trouble to contend with
in the arrangement and distribution OF pipes, as
it increases with the lengths OF The pipes direc ly
and nearly rs with the square Of the velocity OF
wafer passing through them. That is two
lengths OF pipe give twice the trictiona re-
sstancc that one gives, and doubling the velocity
in either length quadTuples the resistance in
that length, Now small pp.s have not the
capa 'ity OF large oncs-Io get an equal amount
of wafer through small pipe that can pass
through a larger one in the same time the We
locly of the water passing through the smaller
must necessarily be made to exceed the velocity
OF lie water passing through the larger.
Far example, ii you refer Ia the accompany
ing hylrauc table Of heads, you will SCI that
inch pipe to pass 900 : .llons per minute, the
amount OF water necessary TO supply Tallahas-
see, rs heretofore stated would ave to discharge
with velocity of 15 81 feet per second, aud To
do so The water would b I'VE to press with AN ef
lecive head of 244 rs feet tor every thousand feet
