Calculating Velocity with Bulk Modulus and Modulus of Rigidity

[sadhu]

proof of
velocity =$$\sqrt{\frac{B+\frac{4*n}{3}}{density}}$$

B bulk modulus
n modulus of rigidity

Are you announcing one or asking for one? Try expressing the bulk modulus and modulus of rigidity in terms of Young's modulus and Poisson's ratio, and assume the Poisson's ratio is zero.
