The 'Radial System' of water distribution is characterized by
- AWater being forced from the periphery to the center
- BA central main pipe with branches spreading out like a tree
- CDividing the city into zones with a reservoir at the center of each zoneCorrect
- DA continuous loop of pipes encircling the entire city
Solution
Concept
Radial system of water distribution
Formula
NONE
Step-by-step solution
1. In water distribution planning, networks are configured according to urban topography. 2. The radial system divides the supply area into discrete operational zones. 3. Each zone features a centrally located elevated reservoir with distribution pipes radiating outward. 4. Hence, option C correctly describes the radial system. Answer: C
Explanation
In the radial layout of water distribution networks, the urban supply district is divided into separate zones with a centralized elevated service reservoir in each zone. Water pipelines radiate outward from the central reservoir toward the periphery, enabling uniform pressure head and streamlined hydraulic calculations.
Why the other options are wrong
A) Flow moves outward from center to perimeter, not from periphery to center. B) A central trunk with branching laterals describes the dead-end system. D) A ring encircling the city describes the circular or ring system.
Shortcut
Radial system = City divided into zones with central reservoir radiating pipes outward.
Common mistake
Confusing radial system with dead-end (tree) or gridiron systems.
Correct answer: C) Dividing the city into zones with a reservoir at the center of each zone
