WebThis is exactly the form of Gardner's relation, with c1 = ¼ and c2 = 0, and the substitution of Equation (1) is precisely what Smith and Gidlow proposed. Such a simple manipulation is not possible with other empirical density-velocity relations. There are a variety of changes one could propose and still retain the essential form of Gardner's ...

H. F. Gardner and L. W. Gardner, is an empirically derived equation that relates seismic P-wave velocity to the bulk density of the lithology in which the wave travels. The equation reads: ρ = α V p β. where ρ is bulk density given in g/cm 3, V p is P-wave velocity given in ft/s, and ... dhvani bhanushali net worth 2021
