QUESTION: 1

### The suitable layout for a water supply distribution system, for an irregularly grown town, is

Solution:

In the dead end system, which is also sometimes called Tree system, there is one main supply pipe, from which originates (generally at right angles) a number of submain pipes. Each submain, then divides into several branch pipes, called laterals. From the laterals, service connections are given to the consumers. This type of layout may have to be adopted for older towns which have developed in a haphazard manner, without properly planned roads.

QUESTION: 2

### The suitable layout for a water supply distribution system, for a city of roads of rectangular pattern, is

Solution:

Grid-iron system; In this system; which is also known as Interlaced system or Reticulation system, the mains, sub-mains and branches are all inter-connected with each other in a well planned city or a town, the roads are generally developed in a grid-iron pattern, and the pipe lines in such places can follow them easily.

QUESTION: 3

### The method, which is most widely used for analysing and designing the pipes of all types of complex water distribution networks, is:

Solution:
QUESTION: 4

Which one of the following pairs is not correctly matched?

Solution:

Check valve does not allow flow in reverse directions

QUESTION: 5

Reciprocating pumps are suitable for

Solution:

Reciprocating pump gives constant discharge under variable heads. It is used for low discharge under variable high heads.

QUESTION: 6

Which one of the following valves is seldom used in water distribution systems because of high head loss characteristics?

Solution:
QUESTION: 7

Sonoscope is used for which one of the following?

Solution:
QUESTION: 8

Consider the following statements:
In a water supply system,
1. drain valves are provided at elevated or higher, points to remove accumulated air.
2. reflux valve allows flow in one direction only.
3. drain valves are provided at low points to remove silt and other deposits.
Which of these statements is/are correct?

Solution:

Drain valves are provided to remove the entire water from within a pipe (after closing the water supply). These are small gated off-takes which are provided at low points. These are also known as blow off valves or scour valves.

QUESTION: 9

Consider the following statements:
The disadvantages of employing steel pipes in conveyance and distribution of water are, they
1. cannot withstand high negative pressures or vacuums that may be created in them, especially the combined effects of vacuum and external loads of backfill and traffic.
2, are easily affected by acidic or alkaline waters and even atmospheric agencies may produce adverse effects on them.
3. cannot be used for high pressures. (Generally not used for pressures above 7 kg/cm2)
Which of these statements is/are correct?

Solution:
QUESTION: 10

The connection of service pipe with municipal water mains supplying water to a building comprises of
1. stopcock
2. gooseneck
3. ferrule
4. water meter
The correct sequence of these is

Solution:

Ferrule: A ferrule is a right angled sleeve made of brass or gun metal, and is joined to a hole drilled in the water main.
Goose neck: Goose neck is a small sized curved pipe made of a flexible material (usually lead) forming a flexible connection between the water main and the service pipe.
Service pipe: Service pipe is a galvanised iron pipe of size less than 50 mm dia. The service pipe which supplies water to the building through the municipal main is thus connected to the main through the goose neck and ferrule.
Stop cock: The stop cock is provided before the water enters the water meter in the house.
