Question

For a constant hydraulic stress on an object, the fractional change in the object’s volume $\left( \frac{\Delta V}{V} \right)$ and its bulk modulus (2) are related as

• A. $\frac{\Delta V}{V}$∝ B
• B. $\frac{\Delta V}{V}$∝ B^-1
• C. $\frac{\Delta V}{V}$∝ B²
• D. $\frac{\Delta V}{V}$∝ B^-2

Answer 1

Answer: (B)

$\frac{\Delta V}{V}$∝ B^-1

Answer 2

B = $B = \frac{P}{\frac{\Delta V}{V}}$
