Of the pressure vessels, with same thickness but different diameters, which one withstands higher pressure ?
Correct answer: B. Smaller dia vessel
- A. Larger dia vessel
- B. Smaller dia vessel
- C. Larger dia long vessel
- D. Strength of the vessel is same irrespective of the diameter
Explanation
For a cylindrical pressure vessel, hoop stress is proportional to the vessel diameter at a fixed wall thickness and pressure. Thus, the smaller-diameter vessel can withstand the higher pressure.
