13. Some figures

A moment later, we were sitting on a couch in the living room, with a cigar in
mouth. Captain mos-lock me a picture with the plane, section and elevation of Nauti-lus.
He began his description in these terms:
? Here, Professor Aronnax, the different dimensions of the boat that is. You see,
It is an elongated, tapered cylinder ends. Thus has the shape of a cigar, the
it has already been adopted in London in several cons-tions of the same gender. The
length of this cylinder, from end to end, is seventy meters and its beam, most
width, is eight meters. It is not built, then, with the same proportions as the
faster go-pores, but their lines are long enough and way
long enough for the displaced water easily and salt-ga not oppose
no obstacle to his departure. These two dimensions allow you to get by a simple
calculating the surface area and volume of the Nautilus. Its surface comprises thousand one hundred meters
square forty five cen-tésimas: volume, 1500 cubic meters and two
tenths, which is to say that in total immersion des-square or weighs 1500
cubic meters or tons.
"In making this boat planes, destined for a na-gation submarine, it was with the
intention that equi-librium in the water remain immersed in their nine tenths
parts. Therefore, in such conditions should not des-displacing more than nine tenths
of its volume, ie 1356 meters and forty-eight centimeters,
or what is the same, that it weighed more than the same number of tons. This forced me to
not exceed that weight to build according to these dimensions.
"The Nautilus is composed of two hulls, one internal and one external, gathered together by
T-shaped irons, which gives extreme rigidity. Indeed, thanks to this provi-tion
cell resists like a block, as if it were solid. Your joints may not assign, is
attach themselves and not for their rivets, and the homogeneity of its construction,
perfect fit due to its material, allows you to de-safiar the n-ore violent seas.
"These two cases are made of sheet steel, whose density relative to
Water is seven to eight déci-mas. The first no less than five centimeters
It is-thickness and weighs three hundred ninety-four tons and Noven-ta-six cents. The
second, with the keel with his fifty centimeters high and twenty wide
alone weighs sixty two tons, machinery, ballast, various accessories and
installations, interior partitions and vi-rotillos, weighs nine hundred sixty
one ton sixty two cents, which added to the three hundred ninety-four
Ninety-six tonnes cents away from the first, the total demanded form thousand
Three-hundred fifty-six tons forty eight cen-tésimas. Do you understand?
? Understood.
? So? He continued the captain ?, when the Nautilus is afloat in these conditions,
one tenth of my-mo is out of water. Now, if you install a
deposits of a capacity equal to that tenth-cir is, containing one hundred
se-fifty tons with tent and two hundredths, and were full of water, the boat will weigh or
then move thousand five hundred and seven tons was completely immersed-Llara. AND
this is what happens, professor. These tanks are installed in the part infe-rior
the Nautilus, and keys to open the fill and ship-da awash.
? Well, Captain, but here we come to the real dif-tad. Your boat can stay
awash, the com-prendo. But below, to dive deeper, right-tra It is located in the
submarine with a pressure device to communicate a boost from the bottom up, evaluated
in an atmosphere of thirty feet of water, that is, about one kilogram per centi-meters
Square?
? Yes, indeed.
? Then, at least not completely fill the Nautilus, I do not see how you can get
take it to the depths.
? Lord teacher, said Captain Nemo, not to be confused with static
dynamic, if not want one expo-nerse to serious errors. It costs very little to achieve low
regions of the ocean, as the bodies are prone to depth. Take my
reasoning.
? I hear you, captain.
I When I raised the problem of determining the weight au-ment had to give the
Nautilus to dip-lo, I did not have to worry about more than reducing vo-lumen
suffering seawater as their layers are becoming more profound.
? It is obvious.
? Now if it is true that water is not absolutely incompressible, it is not less
which it is very little compression-ble. Indeed, according to the latest calculations, this
buy-pressure is not more than four hundred thirty-six diezmillo-nésimas by atmosphere,
or what is the same, for every thirty feet deep. If I want to descend a thousand
me-ters, have to take into account the reduction in the volume under a pressure equivalent
to a water column of thousand meters, that is, under a pressure of one hundred atmospheres.
This reduction will in this case four hundred thirty-six hundred thousandths.
Consequently, I must increase the weight until five hundred thirteen thousand and seventy tons
seven hundredths, rather than fifteen hundred seven tons and two tenths. Increasing not
It will therefore be more than six tonela-das and fifty-seven hundredths.
? So alone?
? Only, Professor Aronnax, and the calculation is easily veri-ficable. Now, I have
supplementary deposits able to embark hundred tons. I can well go down to
considerable depths. When I want to go up and come to the surface, is enough for me
expel the water, whole-mind and empty all deposits if I wish the Nautilus emerges
in his tenth on the water surface.
In such reasonings figures nothing I could object.
? I admit your calculations, Captain? Replied ?, and would show bad faith in discutilos, since
experience gives reason every day, but I fear that we are now at presen-CIA
a real difficulty.
? What?
? When you finds a thousand meters deep, the walls of the Nautilus must
withstand a pressure of one hundred atmospheres. If you decide at that time you empty your
de-deposits supplemental to lighten your boat and rise to the surface, pumps
will have to overcome the pressure of one hundred atmospheres or what is the same, one hundred
kilograms per square centimeter. Well, that calls for a po-tance.
? That electricity could only give me? Rushed to de-cir Captain Nemo ?. I repeat
the dynamic power of my equipment is almost infinite. Nautilus pumps have
prodigious strength, so you could check how-do saw columns of water
rushing like a torrent over the Abraham Lincoln. On the other hand, I'm no good for me
additional deposits to reach more than half of profundi-ties to 1500
two thousand meters, in order to protect my gadgets. But when I have a fancy to visit
the deep ocean, two or three leagues below the surface, employment
longer but no less infallible maneuvers.
-What, Captain?
? This course forces me to reveal how the Nautilus is handled.
? I am eager to know.
? To rule this boat to starboard or port, for mo-view, in short, in a plane
horizontal, pour myself a wide shovel ordinary rudder fixed to the rear of the co-Daste,
which it is driven by a wheel and po-system you read. But I can also move to
Nautilus bottom-up and top-down, ie, in a vertical plane, by means of two
inclined planes attached to their sides on the center of buoyancy. These are planes
phones capable of taking any position and are operated from the inside
through powerful levers. If these planes are parallel to the boat, this is
moves horizontally-mind. If they are inclined, the Nautilus, driven by his he-lice, climbing or
low, according to the arrangement of the inclination, if the diagonal-guiendo that interests me. Yes
will also return more quickly to the surface, do have to engage the
propeller for the water pressure make the Nautilus rise vertically like a balloon
drogen bursting with hi-rises quickly in the air.
? Great, Captain! But how can the steersman follow the path that you set in
through water?
? The helmsman is housed in a glass booth with lenticular crystals protruding from
upper cas-co Nautilus.
-¿Cristales? And how can you resist such pressures?
? Perfectly. The glass, which is fragile to cho-ques, provides, however, a
considerable resistance. In fishing experiences with electricity made in 1864 in the
North Sea, has seen glass plates is a seven-millimeter thickness
only, they resisted a pre-pressure of sixteen atmospheres, while letting go
poten-tes heat radiation will heat unevenly distributed. Well, the
I serve crystals I have a thickness not less than twenty-one at its center
centimeters, ie thirty times more than those.
? Well, I must admit, Captain Nemo; but in the end, it is necessary to see that the Alarm light
darkness, and I ask myself how pre-amid the darkness of the waters ...
? In a cabin at the rear it is housed a powerful electric reflector,
whose rays illuminate the sea to a distance of half a mile.
? Great, Captain! Now I understand that phosphoresce-cia course both narwhal
He has intrigued scholars. And by the way ,,, asked whether the approach of the Scotia
Nautilus, that so much attention was or not the result of an accidental collision.
? Absolutely fortuitous. I sailed two meters deep when there was the
shock, which, as I could see, had no serious consequences.
? Indeed. But what about his encounter with the Abraham Lincoln?
? Lord teacher, sorry for one of the best ships of the US Navy brave,
but I was attacked and had to defend myself. However, I simply put the frigate was-ra
combat. It will not be difficult to repair their damage to the nearest port.
? Ah !, commander? Exclaimed with conviction ?, your Nauti-lus is truly
wonderful.
Yes, Professor? Responded with genuine excitement Captain Nemo ?, and for me
as an organ of my body. The man is subject to all the dangers
so-ber him hover on board any of your ships committed to the hazards of the
oceans, on its surface tie-ne first impression as the feeling of the abyss,
as he has been said so rightly Dutch Jansen, but below the surface and
aboard the Nautilus man has no nin-gun concern. There is fear in him
some deformation, because the double hull of this ship has the rigidity of iron; You do not have
rigs that can tire the rolling and pitching movements exist here; or
Candles can take the wind; or boilers that can explode in the pre-pressure steam;
or fire hazards, since everything is made with steel plates; coal or

since it is the only one who navigates the waters pro-sleeves; or defy storms, and
to a few meters below the tranquility reign supreme surface. Yes, this
It is the ultimate vessel. And if it is true that the engi-ro has more confidence in the boat
the builder, and this more than the captain himself, you understand trust with
I abandon myself to my Nautilus, since I am both its captain, its builder and
engineer.
Transfigured by the ardor of his gaze and passion of his gestures, Captain Nemo had
said that with irresistible eloquence. Yes, he loved his ship like a father loves his
son. But this raised a question, perhaps indiscreet, but I could not resist
formulársela.
? Is it, then, engineer, Captain Nemo?
Yes, professor. I did my studies in London, Paris and New York, at the time
I was an inhabitant of terrestrial continents.
? But how could build this wonderful Nautilus in secret?
? Each of his pieces, Professor Aronnax, has come to me from a different point of Globe
with different names for the recipient. Her keel was forged in Le Creusot; your tree
propeller, Pen and Co., London.; hull plates in Leard, Liverpool; his
propeller, Scott, Glasgow. Its de-deposits were manufactured by Cail & Co., Paris.; his
maqui-nary, by Krupp in Prussia; the ram, by workshops Motala, Sweden; their
precision instruments by Hart Brothers, New York, etc., and each of these
It provides -mers received my plans under different names.
? But these separate pieces had to assemble and Adj-tarlas? I said.
? To this, professor, I had set my workshops on a desert island, in the
Ocean. There, my workers, that is, my brave fellow, whom I instructed and
how-do, and I ended our Nautilus. Then, once end-da operation,
fire destroyed all trace of our passage through the island, which would have blown up power
do.
So constructed, it seems logical to estimate the cost price of the vessel must have been
cuantiosísimo.
? Lord Aronnax, a ship of iron costs 1125 francs per ton.
Well, the Nautilus des-square fifteen hundred. Its cost has therefore risen to a my-Llon
six hundred and eighty-seven thousand five hundred francs; two million with furniture and
four or five million works of art and collections it contains.
? One last question, Captain Nemo.
? You say.
? Are you rich, right?
? Immensely, professor. I could pay without diffi-culty ten billion
francs ascending the deu-da of France.
I peered at me so strange character who spoke. ¿Perhaps he abused my credulity?
The future was to say-melo.
