Estimate the change in the density of water in ocean at a depth of 400 m below the surface. The density of water at the surface 1030 kg m -3 and the bulk modulus of water = 2 × 10 9 N m -2 .

Question

Philoid · Accepted Answer

2 kg m^-3

Given, density at surface,

bulk modulus of water,

Depth of water,

Pressure at this depth,

The bulk strain at depth h is

Now, density at depth h is

Here, V’ is compressed volume at depth h and is given by

Hence, change in density is

Estimate the change in the density of water in ocean at a depth of 400 m below the surface. The density of water at the surface 1030 kg m-3 and the bulk modulus of water = 2 × 109 N m-2.
