Normally, the plate thickness of the bottoms and roofs of vertically cylindrical storage vessels as compared to that of the cylindrical shell is____________?
Correct answer: B. Less
- A. More
- B. Less
- C. Same
- D. More or less depending upon the pressure & temperature inside the vessel and the nature of
- E. the fluid contained therein
Explanation
The cylindrical shell must withstand the liquid head and hoop stress over the vessel height, so it is normally thicker than the roof and bottom plates. Therefore, the bottoms and roofs are generally less thick than the shell.
