The longitudinal (P-wave, compressional) velocity in a rock can be estimated from its Young's modulus (E) and density (rho) using the relation Vp = sqrt(E/rho), a standard simplified elastic-wave-velocity formula used in rock mechanics and geophysics.
Using the relation Vp = sqrt(E/rho), with the rock's Young's modulus E = 9.72 megabars and density rho = 2.7 g/cm^3 (expressing E appropriately in...
