• # question_answer From design point of view, spherical pressure vessel are preferred over cylindrical pressure vessels because they: A) Are cost effective in fabricationB) Have uniform higher circumferential stressC) Uniform lower circumferential stressD) Have a larger volume for the same quantity of material used

$\frac{{{({{\sigma }_{\theta }})}_{sphere}}}{{{({{\sigma }_{\theta }})}_{cylinder}}}=\frac{pd}{4t}\times \frac{2t}{pd}=\frac{1}{2}$
