A cylindrical pressure vessel of volume 6 πm3 has to be designed to withstand a maximum internal pressure of 10 atm. The allowable design stress of the material is 125N/mm2 and corrosion allowance is 2 mm. The thickness of the vessel for a length/diameter ratio of 3 will be close to________________?
Correct answer: D
Explanation
Using the given volume and L/D ratio to find dimensions, then applying pressure vessel formulas leads to a thickness close to 10 mm.
