the average depth of indian ocean is about 3000m.Thevalue of frictional compression `((DeltaV)/V)` of water at the bottom of the ocean is (given that the bulk modulus of water is `(2.2xx10^(9)Nm^(-2),g=9.8ms^(-2),PH_(2)O=1000kg.m^(-3))`

Explanation

The pressure exerted by a 3000 m column of water on the bottom layer
`p=hrho" g"=3000" m"xx1000" kg m"^(-3)xx10"m s"^(-2)`
`=3xx10^(7)" kg m"^(-1)" s"^(-2)`
`=3xx10^(7)"N m"^(-2)`
Fractional compression `DeltaV//V`, is
`DeltaV//V=" stress/B"=(3xx10^(7)" N m"^(-2))//(2.2xx10^(9)" N m"^(-2))`
`=1.36xx10^(-2)` or `1.36%`
