A vertical offshore structure is built to withstand a maximum stress of 10^(9) Pa . Isthe structure suitable for putting up on top of an oil well in the ocean ? Take the depth of the ocean to be roughly 3 km , and ignore oceancurrents . |

Answer» Solution :Here , h=3km=3000m `RHO` (density of WATER)`=10^(3)kg//m^(3)` The pressure exerted by sea water `P=hrhog` `P=(3000)(1000)(9.8)` `P=2.94xx10^(7)Pa` Pressure in the sea at a depth is about `3xx10^(7)` Pa . Hence , STRUCTURE willbe suitable for putting upon top of an oil well provided the pressure exerted by sea water is LESS than the maximum stress of `10^(9)` Pa it canbear . Pressure DUE to sea water is `3xx10^(7)` Pa since the pressure of sea water is less than the maximum. |
