Solution:

If we apply Darcy's law to seepage velocity instead of discharge velocity, the constant introduced to remove proportionality will be known as:

Coefficient of Permeability

Coefficient of Percolation

Coefficient of Uniformity

None of the above

Solution:

A drainage pipe becomes blocked with sand for a certain length. The permeability of the sand is 8 × 10^-4 cm/s. The discharge under a head difference of 20 m is found to be 0.2 m³ per day. The cross-section of the pipe is 180 cm². Determine the length of the pipe blocked by the sand.

Solution:

A fully submerged infinite sandy slope has an inclination of 30° with the horizontal. The saturated unit weight and effective angle of internal friction of sand are 18 kN/m³ and 38°, respectively. The unit weight of water is 10 kN/m. Assume that the seepage is parallel to the slope. Against shear failure of the slope, the factor of safety is
