WATER PRESSURE
Tremendous Force Exerted at
the Bottom Of the Sea.
AIR THERE COULD NOT RISE.


ps6ree Of Density BY the Enormous
Weight That The Water Would Float
Upon lt-Limits Of Diving Depths.
From ordinary considerations II
would seem that there is no limit to
the depths to which a diver or a sub
marine boat might go. Such. how
ever. is not the case. What prevents
diving to great depths Is the enormous
~ increasing pressure Of water. No
diver without suit can go over $50
feet. because the pressure on the body
Is then about I'VE tons to the square
foot on his body Eardrums would be
STAYED in. and other fearful difficulties
would result
TO remedy this the diving suit was
Invented, but there Is limit. also to
Its depth. At depth of one mile the
pressure due to the water alone is 1876
tons to the square foot. Even Il a div
Ing suit was devised to Withstand this
enormous pressure trouble would be
found In getting a pipe line that long
and withstanding the pressure that
would not break Of its own weight
In the case Of a submarine boat 1t
Is slightly different Here only the
strength Of the boat Is the necessary
thing But to be strong the walls have
to be fhickened. and this adds to the
weight, Consequently adding to the
load to be pulled through the water,
