A cylindrical storage tank can have a self supported conical roof ?
Correct answer: A. If its diameter is less than 15-20metres
- A. If its diameter is less than 15-20metres
- B. If its diameter is more than 50 meters
- C. If the thickness of the roof is more than that of the cylindrical shell
- D. Irrespective of its diameter
Explanation
A self-supporting conical roof is practical for relatively small storage tanks, commonly when the diameter is below about 15 to 20 m. Larger tanks usually require structural support for the roof.
