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 $37.29$ $80.20$ $68.25$ $0.03$

A constant-head permeability test was conducted on a soil specimen under a hydraulic gradient of $2.5$. The soil specimen has specific gravity of $2.65$ and saturated water content of $20\%.$ If the coefficient of permeability of the soil is $0.1\: cm/s$, the seepage velocity (in $cm/s,$ round off to two decimal places) through the soil specimen is ________.

The seepage occurring through an earthen dam is represented by a flownet comprising of $10$ equipotential drops and $20$ flow channels. The coefficient of permeability of the soil is $3 \: mm/min$ and the head loss is $5 \: m$. The rate of seepage (expressed in $cm^3/s$ per $m$ length of the dam) through the earthen dam is _________
