P-wave velocity of the high-frequency limit of the Biot approach in dependence of the tortuosity using the estimated dry moduli for the two saturation scenarios. With the numerically determined P-wave velocities 1667 m \({s}^{-1}\) and 1851 m s\({}^{-1}\) we can estimate the free parameter tortuosity for water and high-density fluid saturation, respectively.
