Velocity of bulk compressional waves

Input(s)

E: Young's Modulus $\left(\mathrm{lbf} / \mathrm{ft}^{2}\right)$

$\rho$: Density $\left(\mathrm{lbm} / \mathrm{ft}^{3}\right)$

$\mu$: Poisson's Ratio (dimensionless)

Output(s)

$V_{b}$: Velocity of Bulk Compressional Waves $(\mathrm{ft} / \mathrm{s})$

Formula(s)

$$ \mathrm{V}_{\mathrm{b}}=\left(\frac{\mathrm{E}}{\rho} * \frac{1-\mu}{(1+\mu) *(1-2 * \mu)}\right)^{0.5} $$
