The sinking of the Titanic remains one of the most
famous maritime disasters in history and has captured public interest and
attention for over a hundred years.
The RMS Titanic was a British passenger liner
that embarked on its maiden voyage from England on April 10, 1912,
bound for New York City in the United States. It made brief stops at Cherbourg,
France, and Queenstown (now known as Cobh), Ireland, to pick up additional
passengers.
Shortly before midnight on April 14th, 1912, the
Titanic, at the time the world’s largest passenger ship, struck an
iceberg, and a few hours later completely sank in the icy waters of
the Northern Atlantic Ocean.
There were 2,224 passengers on board the
ship, of which around 1,500 died after striking the iceberg.
The most famous shipwreck
The wreckage of the Titanic was discovered on
September 1, 1985, by a joint French-American expedition led by Jean-Louis
Michel of IFREMER (French Research Institute for Exploitation of the Sea) and
Dr. Robert Ballard of the Woods Hole Oceanographic Institution. The shipwreck
lies at a depth of about 12,500 feet (3,800 meters) on the ocean
floor.
Since its discovery, salvagers and
researchers have dived to the depth of 12,500 feet (38100 metres / 3.81
km) where the remains of the Titanic are located. It's final resting place is
almost 600km off the coast of Newfoundland, Canada in the North Atlantic Ocean.15
It is the at the same site and depth as the deep-sea
submersible carrying five people on a voyage to the century-old wreck of the
Titanic was found in pieces from a “catastrophic implosion” that killed
everyone aboard, the US Coast Guard said yesterday, ending a multinational
five-day search for the vessel.
This give me an idea what was the seabed pressure at the
depth where the deep-sea tourist submersible imploded?
Let’s check this out:
Density of seawater is between 1.02 and 1.03 g/cm3
(1.025 g /cm3) or 1026 kg / cubic metres.
Hence the water pressure where both the titanic sank
and the deep- seas tourist submersible imploded was:
P = ρ g h
Where,
- P = water pressure in
Pa
- ρ = density of water
in kg.m-3
- g = gravitational
force in 9.81 m.s-2
- h = height in m
= 383,478,786 Pa or approximately 383,479,000 Newton
per square metre
= 39,104,099 kilograms per
square meter
(1 pascal × 0.101972 = kg m3)
The atmospheric pressure at sea level is 30 inches of mercury (Hg)
= 760 mm
Hg
=1013.25
millibars
= 10,332
kg per square meter
This means
that water pressure at the bottom of the of the ocean floor where the Titanic sank,
and the tourist Titan submersible imploded is whopping 3,785 times greater than
the atmospheric pressure here on our surface. It is little wonder why the Titan
submersible would not be crushed inside under such tremendous water pressure?
Suppose this Earth turns into a black hole (it will
never) unless its mass is 3 – 5 times that of the Sun, then this Earth will
collapse to the size measuring:
Rs = 2GM / c^2
= 2. x 6.6738×10−11 m3⋅kg−1⋅s−2 x 5.972 ×
10^24 kg / (299792458 m⋅s−1)2
= 8.869 x 10 ^-3 meters (0.008869 m)
= 0.887 cm in radius or 1.8 cm in diameter which is
slightly less than half the size of a ping pong ball
It would exert a pressure of 5.972 × 10^24 kg / 4 pi r^2
= 5.972 × 10^24 kg / 4 pi (8.869 x 10 ^-3 meters)
^2
=5.972 × 10^24 kg /9.8846 ^-4
= 6 x 10 ^27 kg per sq. metre
where,
Mass of Earth is 5.972 × 10^24 kg.
G = gravitational constant (6.6738×10−11 m3⋅kg−1⋅s−2
C = speed of light in a vacuum (299792458 m⋅s−1)2
The black hole of Earth would be 1.5 x 10^20 (15,0 000
000 trillion times) greater than the water pressure at the bottom of the seabed
where the Titanic sank.
(Surface area of the sphere = 4 pi r ^2,
where “r” is the sphere's radius)
Just a sober thought for the souls who died in the Titanic and Titan tragedy.
