The bow hit the bottom at a speed of about 20 knots (10 metres per second), digging about 60 feet (20 m) deep into the mud, up to the base of the anchors. The impact bent the hull in two places and caused it to buckle downwards by about 10° under the forward well deck cranes and by about 4° under the forward expansion joint .
Shortly afterwards, as a result of the Guinness organization’s change of regulations to being less restrictive, the record was awarded to a Hungarian diver and mountaineer Erno Tósoki dived a maximum of 2 meters (6.6 ft) deep, for about 10 minutes on altitude 6,382 meters (20,938 ft).
The US Navy air decompression tables allow flying with a cabin altitude of 8000 feet for repetitive group C, which results from a bottom time of 61 to 88 minutes at a depth of 15 feet (4.6 m), or a bottom time of 102 to 158 minutes at a depth of 10 feet (3.0 m).
To help compare different orders of magnitude, this section lists lengths between 10 −7 and 10 −6 m (100 nm and 1 μm). 100 nm – greatest particle size that can fit through a surgical mask [80] 100 nm – 90% of particles in wood smoke are smaller than this. [citation needed] 120 nm – greatest particle size that can fit through a ULPA ...
Therefore, mean depth figures are not available for many deep lakes in remote locations. [9] The average lake on Earth has the mean depth 41.8 meters (137.14 feet) [ 9 ] The Caspian Sea ranks much further down the list on mean depth, as it has a large continental shelf (significantly larger than the oceanic basin that contains its greatest depths).
In the United States the pace is an uncommon customary unit of length denoting a brisk single step and equal to 2 + 1 ⁄ 2 feet or 30.0 inches or 76.2 centimetres. [ 3 ] [ 4 ] The Ancient Roman pace ( Latin : passus ) was notionally the distance of a full stride from the position of one heel where it raised off of the ground to where it set ...
A wide variety of sources [4] [5] [6] define LEO in terms of altitude.The altitude of an object in an elliptic orbit can vary significantly along the orbit. Even for circular orbits, the altitude above ground can vary by as much as 30 km (19 mi) (especially for polar orbits) due to the oblateness of Earth's spheroid figure and local topography.
A fathom is a unit of length in the imperial and the U.S. customary systems equal to 6 feet (1.8288 m), used especially for measuring the depth of water. [1] The fathom is neither an international standard (SI) unit, nor an internationally accepted non-SI unit.
