The submersible named, Titan , operated by OceanGate is said to have destroyed due to catastrophic implosion in the North Atlantic Ocean en route to see the wreckage of  Titanic ship that sunk in the ocean in 1912.  More to understand      Titanic wreckage is at the depth of 4000 meters (4km) below the surface of the ocean. While, atmospheric pressure at the surface of the ocean is 14.7 pounds per square inch (psi) or 100 kilopascals, at the depth of 4000 meters below the surface, the water pressure is considered around 6000 (psi) or 41,000 kilopascals. Under such a huge pressure, even a minute structural flow would cause catastrophic implosion.   Why is it in news ?      Recently five people including the British billionaire
