The average depth of ocean is 2500 m. Calculate the fractional compression (ΔV/V) of water at the bottom of ocean, given that the bulk modulus of water is 2.3 × 109 N/m2.
Pressure exerted at the bottom layer by water column of height h is
P = hρg = 2500 × 1000 × 10
= 2.5 × 107 N/m–2
= Stress
= 1.08%
