The ship sank soon after the collision on April 14, 1912, and now rests on the sea floor at a depth of 12607 ft. Recently, the wreck was explored by the research vessel Nautile, which has successfully recovered a variety of items from the debris field surrounding the sunken ship. Calculate the pressure in atmospheres and pounds per square inch exerted on the hull of the Nautile as it explores the sea bed surrounding the Titanic.
