-
Give the different shapes of the surface drains and
state where they are adopted. (Sharp

8.
What is a surface drain? What are the good requirements
of surface drain? (Sharp series pg.36,
& 37)
9.
What do you understand by self-cleaning velocity or
limiting velocity? (Sharp series pg.7)
10. What

the different types sewers classified on the basis of material used. (Sharp series pg.28, 29)
12. Distinguish
between Domestic & Industrial sewage. (Sharp
series pg.6)
13. Distinguish
between Infiltration & Exfiltration.
. Infiltration is used to indicate
the leakage of water into the sewer, whereas exfiltration indicates the leakage
of sewage from sewers to ground.
Infiltration
|
Exfiltration
|
Leakage of water from the ground surrounding the sewers
|
Leakage of sewage into the ground surrounding the sewer
|
The exfiltration pollutes the underground water
|
The infiltration unnecessarily increases the quality of
sewage.
|
14. Distinguish
between Dry weather flow and wet weather flow. (Sharp series pg.9)
15. What
are the process of laying and testing of sewers? (Sharp series pg.30 & 31)
16. State
the significance of D.O, B.O.D, C.O.D, pH value, chlorides. (Sharp series pg.20 & 21)
Note: Refer the previous question papers
for more detailed information.
