Question

Give reason for the below:

Pipes carrying hot water are not straight but looped. Why?

Answer 1

Pipes carrying hot water are not straight but looped because:

1. Metal pipes in general expand and contract on heating and cooling respectively.
2. While carrying hot water, the pipes may bend or break due to the expansion (by hot water) and contraction (by the cold air of the atmosphere).
3. The pipes carrying hot water are looped to reduce the stress on pipes due to expansion and contraction.

Hence, the pipes carrying hot water are not straight but looped.
