Vedclass · Answer

(B) The bulk modulus $(B)$ is defined as the ratio of hydraulic stress to the volumetric strain.$B = \frac{	ext{Stress}}{	ext{Volumetric Strain}} = \frac{	ext{Stress}}{\Delta V / V}$Rearranging the formula to solve for the fractional change in volume $(\Delta V / V)$:$\frac{\Delta V}{V} = \frac{	ext{Stress}}{B}$Since the hydraulic stress is given as a constant,the relationship between the fractional change in volume and the bulk modulus is:$\frac{\Delta V}{V} \propto \frac{1}{B}$

For a constant hydraulic stress on an object,the fractional change in the object's volume $(\Delta V/V)$ and its bulk modulus $(B)$ are related as
