Verified Answer
Consider the following statements:1. Seepage force is applied by flowi...
Seepage force is due to frictional drag and its magnitude is given by iYw per unit volume of soil. For quick condition during upward flow.
Effective stress = total stress - pore pressure So statement 1 and 3 is correct.
Effective stress = total stress - pore pressure So statement 1 and 3 is correct.

Seepage Forces, Quick Sand Condition, and Their Relationship:
Seepage force is the force applied by flowing water to the soil skeleton through frictional drag. The magnitude of seepage force per unit volume of soil at any point is equal to Yw/i, where Yw is the unit weight of water and i is the hydraulic gradient at that point. In a soil mass subjected to upward flow of water, quick sand condition develops when pore pressure is equal to the total stress. Let's discuss each statement in detail:
1. Seepage force is applied by flowing water to the soil skeleton through frictional drag:
Seepage force is the force applied by the flowing water to the soil skeleton through frictional drag. It is caused by the flow of water through soil pores and interstices. The water molecules exert a force on the soil particles as they flow through the soil. This force is called the seepage force. It is perpendicular to the flow direction and acts in the opposite direction to the flow. The seepage force is responsible for the movement of soil particles and the erosion of the soil.
2. The magnitude of seepage force per unit volume of soil at any point is equal to Yw/i, where Yw is the unit weight of water and i is the hydraulic gradient at that point:
The magnitude of the seepage force per unit volume of soil at any point is equal to Yw/i, where Yw is the unit weight of water and i is the hydraulic gradient at that point. The hydraulic gradient is the slope of the water table in the direction of flow. It is the ratio of the difference in water levels to the distance between the two levels. The seepage force is directly proportional to the hydraulic gradient. As the hydraulic gradient increases, the seepage force also increases. The unit weight of water is the weight of one unit volume of water. It is a constant that depends on the temperature and pressure of the water.
3. In a soil mass subjected to upward flow of water, quick sand condition develops when pore pressure is equal to the total stress:
In a soil mass subjected to upward flow of water, quick sand condition develops when the pore pressure is equal to the total stress. The total stress is the sum of the effective stress and the pore water pressure. The effective stress is the stress that is transmitted through the soil skeleton. The pore water pressure is the pressure exerted by the water in the pores of the soil. When the pore water pressure exceeds the total stress, the effective stress becomes negative, and the soil loses its strength. This is called the quick sand condition. In this condition, the soil behaves like a fluid, and any object placed on it sinks rapidly.
Conclusion:
In conclusion, the correct option is B, i.e., 1 and 3. Seepage force is applied by flowing water to the soil skeleton through frictional drag. The magnitude of seepage force per unit volume of soil at any point is equal to Yw/i, where Yw is the unit weight of water and i is the hydraulic gradient at that point. In a soil mass subjected to upward flow of water, quick sand condition develops when pore pressure is equal to the total stress.
