A 6 m thick clay stratum has drainage at both its top and bottom surface due to the presence of sand strata. The time to complete $50 \%$ consolidation is 2 years. The coefficient of volume change $\left(m_v\right)$ is $1.51 \times 10.3 \mathrm{~m}^2 / \mathrm{kN}$ and unit weight of water is $9.81 \mathrm{kN} / \mathrm{m}^3$.

The coefficient of permeability (in m/year) is__________ (round off to three decimal places).

In a triaxial unconsolidated undrained (UU) test on a saturated clay sample, the cell pressure was 100 kPa. If the deviatoric stress at failure was 150 kPa, then the undrained shear strength of the soil is _________ kPa. (in integer)
