In this post, I will share some important questions which are frequently asked in competitive examinations such as SSC, UPSC and state PSCs.
-
The joint on cast iron pipes for water supply are generally
- flanged
- welded
- spigot and socket (turned and bored)
- spigot and socket (lead)
-
The valve, which allows the flow only in one direction, is a:
- reflux valve
- sluice valve
- gate valve
- none of the above
-
The valve, which is provided in the water distribution pipes at street corners and pipe junctions to control the flow in the distribution system, is:
- an air valve
- a sluice valve
- a scour valve
- a reflux valve
-
A check valve is also known as a:
- relief valve
- reflux valve
- blow off valve
- none of the above
-
A sluice valve is also known as:
- air-inlet valve
- scour valve
- gate valve
- none of the above
-
Pressure relief valves installed along water mains maybe provided for relieving:
- air pressure
- water hammer pressure
- ice pressure
- all of the above
-
Anchorages in water pipelines are provided:
- at all bends
- at all steep slopes
- at other points of unbalanced pressure
- all of the above
-
Scour valves are provided:
- at the street corners to control the flow
- at the dead ends to drain out the wastewater
- at every summit of the rising main
- at the foot of the rising main along the slope, to prevent back running of water
-
A blow-off valve is provided in a water distribution system, at:
- low points
- high points
- junction points
- all of the above
-
Summits are the point of:
