A pipe is generally made of circular cross-section, because a circular cross-section has the____________________?
Correct answer: A. Both A. & B.
- A. Both A. & B.
- B. Lowest surface area requirement for a given volume
- C. Higher structural strength
- D. None of these
Explanation
A circular section provides high structural strength because pressure stresses are distributed uniformly, and it also gives the least wall surface for a given enclosed volume. Thus, both stated advantages apply.
