Explanation:
In soil mechanics, the concept of total head is used to understand the energy distribution within a soil mass. It is defined as the sum of the hydraulic potential and the velocity energy per unit weight of water measured at any point on the soil.
Hydraulic Potential:
The hydraulic potential represents the energy per unit weight of water due to its elevation or position in the soil. It is analogous to the gravitational potential energy in mechanics. The hydraulic potential is measured in terms of head, which is the height of a column of water that would produce the same potential energy.
Velocity Energy:
The velocity energy represents the energy per unit weight of water due to its motion within the soil. It is analogous to the kinetic energy in mechanics. The velocity energy is measured in terms of head, which is the height to which a column of water would be raised if all its kinetic energy was converted to potential energy.
Total Head:
The total head at any point on the soil is the sum of the hydraulic potential and the velocity energy per unit weight of water. It represents the total energy per unit weight of water at that point. The total head can be used to understand the distribution of energy within the soil, and it is an important parameter in various soil mechanics calculations and analyses.
Therefore, the correct answer is option B) Hydraulic potential. The total head at any point on a soil may be regarded as the hydraulic potential per unit weight of water measured at that point.
