An object is located at 2 km beneath the surface of the water. If the fractional compression $\frac{\Delta V}{V}$ is $1.36 \%$, the ratio of hydraulic stress to the corresponding hydraulic strain will be $\_\_\_\_$ .
[Given density of water is $1000 \mathrm{~kg} \mathrm{~m}^{-3}$ and $\mathrm{g}=9.8 \mathrm{~ms}^{-2}$.]
