the past few years have been. Stupen-
dous. but the constructing engineers
have been hampere6 by the fact that
no precedents existed whereon to base
estimates for the work. No laboratory
was large enough to make tests or
determine data which could be used IL
work of such extensive a character. 1t
is the purpose of the Cornell professors
to furnish this data in such form that
any engineer may take advantage Of
it no matter how extensive the scope
of his enterprise. The plant includes
dam, a canal. a waterfall, a stand-pipe
and a laboratory building. Back of the
dam miniature men-of-war Will be
tested and figured upon just as they
are in the government tank at Wash
ingtOn. In the canal a trolley car
riage will pull boats up the current Of
rushing water, so as to test their ac-
ton under peculiar conditions. The
stand-pipe viii be used for many pur-
poses. chief among which will be the
testing of the friction of water in pipes.
The laboratory building naturally will
have its uses.
The hydraulic laboratory of the Bos-
ton Institute of Technology which is
now the largest in the world, has a
maximum capacity of % cubic feet of
water a second The laboratory at
Cornell is designed to afford maxi
mum capacity of LOO cubic feet per
second The canal is $50 feet long, 16
feet wide and 10 feet deep. 1t has an
impervious lining and it will be used for
improvements upon the rating of cur
rent metres the determination of CO.
efficients of resistances. There are six
head-gates to the canal, controlled by
gate HOSTS which, owing to the widen
ing of the canal at the entrance, Will
enable the full capacity of water to be
passed through the gates There will
L., If 1.
maximum breadth Of 16 feet. The fall
of water from the crest of this weir
to the bottom of the canal when full
will be Is feet. This is to afford OPP
portunity for studying the form of
water Jets The water supply to the
laboratory viii be drawn from stor-
age reservoir covering about 20 acres
and having a storage capacity of over
SO. 00O 900 gallons of water. At the sides
of the canal end are two sets of gates;
one discharginG the flow from the canal
into the gorge, The other leading into
q side canal which in turn leads into
a 6-foot stand-pipe extending into the
gorge below the cliff.
WEIGHING WATER
BY means of castings Of various sizes,
this stand-pipe viii afford opportunity
at its foot, for experimenting upon the
discharge of water through orifices, !
the loss Of the water head through
gates and various other questions con-
nected with the loss of motion, and
friction in pipes. The foot of the
stand-pipe is placed in stone labora-
tory building having the approximate
floor dimensions of % feet by 20 feet.
IL will be fitted with q 12-tOn meaSur-
ing scale. for the accurate determine
tions of water discharge from the orr
fees in the pipe, by means OF weigh
ing The weighing capacity will be
u tons an hour. At the foot of the
stand-pipe a special casting has been
set, having a 36-inch opening, designed |
for making connection with large pipe
lines, to be laid down the body of the
stream This will afford a tangent 1880
feet in length at this point. This is fer
determining the loss by friction from
different forms of connecting plates !
the pressure Of water in pipes and the /
loss of head due to the friction in pipes |
caused by joints, rivets, etc.
The stOrag- reservoir has been form |
ed by the construction of dam hav- !
ing a spillway length during times of
flood of $50 feet. The dam is a concrete
structure &c feet high. 1t is construct /
ed on a curve, having a radius of $50 /
feet. From the gate house at the south I
en6 of the dam is a 4S-inch riveted steel
conduit leads to the power house, sta
tened in the gorge below. This con-
d,,it IS tapped by a 3S-inch steel pipe /
winch crosses the foot of the canal 1t I
discharges into the stand-pipe men /
toned above thus affording bypass,
so that the stand-pipe may be used I
for other purposes without interfer-
ing with the use OF the main canal
