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= h rho g = 3000 m xx 1000 kg m^(-3) xx 10 ms^(-2)`
` = 3 xx 10^7 Nm^(-2)`
Fractional compression `Delta V// V, ` is
`Delta V//V ` =stress / B ` = (3 xx 10^7) // (2.2 xx 10^9)`
`= 1.39 xx 10^(-2)` or 1.36%
