Question
A scuba tank is being designed for an internal pressure of 2,655 psi with a factor of safety of 2.0 with respect to yielding. The yield stress of the steel is 67,000 psi in tension and 25,000 psi in shear. (Assume that the given radius or diameter is an inside dimension
and that all internal pressures are gage pressures.)
(a) If the diameter of the tank is 7.0 in., what is the minimum required wall thickness (in inches)?
0.277
X inches
(b) If the wall thickness is 0.25 in., what is the maximum acceptable internal pressure (in psi)?
2392.85
psi
