If a sewer X is to be designed to generate equivalent self-cleansing action as in sewer Y, then
  • a)
    velocity in sewer X must be equal to velocity in sewer Y
  • b)
    slope of sewer X must be equal to slope of sewer Y
  • c)
    tractive force intensity generated in sewer X must be same as that in sewer Y
  • d)
    the roughness coefficient of X sewer material should be same as that of Y sewer material
Correct answer is option 'C'. Can you explain this answer?

Velocity and discharge are functions of tractive force intensity which depends upon friction coefficient as well as flow velocity. For equal self cleansing tractive force intensity should be same in both sewers.

Explanation:
Self-cleansing is the ability of a sewer to clean itself by the flow of wastewater. It is important to maintain the self-cleansing action of sewers to prevent clogging and blockage of the sewer system. To design a sewer that generates equivalent self-cleansing action as in sewer Y, the tractive force intensity generated in sewer X must be the same as that in sewer Y.

Tractive force intensity is defined as the force required to move a unit area of the wastewater along the surface of the sewer. It is proportional to the velocity of wastewater and the slope of the sewer. Hence, to generate the same tractive force intensity in sewer X as in sewer Y, either the velocity or the slope of sewer X must be adjusted accordingly.

However, adjusting the slope of sewer X may not always be feasible due to the constraints of the site. Therefore, adjusting the velocity of the wastewater is a more practical solution.

Therefore, the correct answer is option C: the tractive force intensity generated in sewer X must be the same as that in sewer Y.
