Question

Determine the velocity of sound in mercury, which has bulk modulus of 2.8×10^10 and the a density of 1.36×10⁴ kg/m³.

Answer 1

V( velocity )= $\sqrt { \frac{B}{\rho}}$

where B= bulk modulus , and $\rho$ = density of the fluid

v= $\sqrt { \frac{2.8\times 10^{10}}{1.36 \times 10^4 }} =$ 1434.8601 m/s
