The fractional compression $\displaystyle \left(\frac{\Delta \mathrm{V}}{\mathrm{V}}\right)$ of water at the depth of $\displaystyle 2.5$ km below the sea level is $\displaystyle \_\_\_\_$%. Given, the Bulk modulus of water $\displaystyle =2 \times 10^9 \mathrm{~N} \mathrm{~m}^{-2}$, density of water $\displaystyle =10^3$ $\displaystyle \mathrm{kg} \mathrm{m}^{-3}$, acceleration due to gravity $\displaystyle =\mathrm{g}=10 \mathrm{~m} \mathrm{~s}^{-2}$.
