Question
A large spherical tank (see figure) contains
gas at a pressure of 420 psi. The tank is 45 ft in diameter
and is constructed of high-strength steel having
a yield stress in tension of 80 ksi.
(a) Determine the required thickness (to the nearest
1/4 inch) of the wall of the tank if a factor of
safety of 3.5 with respect to yielding is required.
(b) If the tank wall thickness is 2.25 in., what is the
maximum permissible internal pressure?
