What factor should the area of overflow drains for gravity water supply tanks be in relation to the size of the supply pipe?

  1. 1

  2. 2

  3. 3

  4. 4

The correct answer is: 2

The correct answer is B. The factor the area of overflow drains for gravity water supply tanks should be in relation to the size of the supply pipe is 2. This means that the area of the overflow drains should be twice the size of the supply pipe. This ratio helps ensure that the overflow drains can handle any excess water in case of a high flow rate or pressure within the system, preventing potential water damage or flooding issues.
