In an Oedometer apparatus, a specimen of fully saturated clay has been consolidated under a vertical pressure of $\text{50 kN/m}^2$ and is presently at equilibrium. The effective stress and pore water pressure immediately on increasing the vertical stress to $\text{150 kN/m}^2$, ... $\text{50 kN/m}^2$ and $\text{100 kN/m}^2$ $0$ and $\text{150 kN/m}^2$

A non-homogeneous soil deposit consists of a silt layer sandwiched between a fine-sand layer at top and a clay layer below. Permeability of the silt layer is $10$ times the permeability of the clay layer and one-tenth of the permeability of ... third of the thickness of the clay layer. The ratio of equivalent horizontal and equivalent vertical permeability of the deposit is _________.

Permeability tests were carried out on the samples collected from two different layers as shown in the figure (not drawn to the scale). The relevant horizontal $(k_h)$ and vertical $(k_v)$ coefficients of permeability are indicated for each layer. The ratio of the equivalent horizontal to vertical coefficients of permeability, is $37.29$ $80.20$ $68.25$ $0.03$
