A constant-head permeability test was performed on a vertical sand column of height 40 cm and cross-sectional area of 25 cm². During the test, when the loss of head was 50 cm, the volume of water collected in 2 minutes was 300 cm³. Applying Darcy's law, the calculated coefficient of permeability of the sand column is \(\underline{\hspace{0cm}}\) cm/sec. (round off to 2 decimal places).
The radius \( r \) of the oblate spheroid at 45° latitude with ellipticity of polar flattening of 1/298.25 and equatorial radius of 6378140 m is \(\underline{\hspace{2cm}}\) km.
The most coaliferous unit of the Gondwana Supergroup is:
A vertical borehole encounters a shale bed of uniform thickness occurring at a depth of 5 m and dipping 60°. The borehole pierces through this shale bed for a length of 10 m to reach a sandstone layer below. The true thickness of the shale bed is \(\underline{\hspace{1cm}}\) m.
If \( \alpha \) and \( \beta \) are P- and S-wave velocities, respectively, then \( \alpha^2 - \frac{4}{3} \beta^2 \) is equal to: \[ (\kappa \text{ is the bulk modulus, } \mu \text{ is shear modulus, and } \rho \text{ is density}) \]
