O. Why does small vertical stream
break into spherical dropS?-A. f.. q.
A. When a liquid flows out OF a
vessel through a circular opening In the
bottom of the vessel, the form OF the
stream is at first nearly cylindsscal
though its diameter gradually dlinin-
ishes from the orif1ce downward on &C
count of the increasing velocity Oh the
LIQUID. But the liquid after it leaves
cept gravity, the pressure OF the air
and its own surface-tenSion. OF these,
gravity has no effect on the form OF
the stream except in drawing asunder
it's partS In a vertical direction, because
the lower parts are moving faster than
the upper parts. The resistance OF the
air produces little disturbance until
the velocity becomes very great. But
the surface-tenSion, acting on cylin-
dric column Of liquid whose length ex-
ceeds the limit of stability, begins TO
produce engagements and contractlons
in the stream as soon as the liquid mas
left the orifice, and these inequalities
in the figure of the column go on in
creasing till it is broken up into elon-
gated fragments. These fragments, as
they are falling through the air, con-
tinue to be acted on by surface-tension.
They therefore shorten themselves, and.
after series of oscillations in which
they become alternately elongated and
fiattened, settle down into the form Of
spherical drops.

@. Where is the longest rubber belt in
use?-S. A. B.
A. The longest rubber belt in opera
ton is part of the dock installation OF
a coal company in Pittsburgh. Pa. It
is 1928 feet long, having been manu-
| featured in 10 sections. Total weight
| is approximately $4,000 pounds, the
rubber content being $4,000 pounds.
The width is 4S inches, of plies OF 81
ounces duck with rubber covers 3-16
| inch and lie inch. This belt was
manufactured in 1922, and 1t Is still In
service The belt operates at 500 feet
| per minute and carries a maximum OF
| 1900 tons of coal per hour. 1t Is eSti-
| mated that since its installation 1t has
carried total Of 100000 to1s OF coal.
@. What are the processes used in
reproducing drawings?-A. Men
| A. Drawings can be reproduced By any
of the three processes of printing.
These three processes are relief print
ing. intaglio printing and photographic
printing In relief printing, the design
is raised above the blank parts which
do not print. In intaglio printing, the
design, is etched below the surface OF
the blank parts which do not print. In
photographic printing. the design to be
printed and the blank parts are on
/ level surface.
@. Are good manners inherent or &C
quired?-D. w. D.
