Concept explainers

Pressure Vessels

The term pressure vessel refers to a closed container that contains gas or liquid at a different pressure than environment pressure. The pressure vessels have a wide scale of applications in our day-to-day lives and other industrial places. Some common examples of pressure vessels are gas cylinders, autoclaves, compressor vessels, etc.

Question

A spherical stainless-steel tank having an inner diameter 620, is used to store natural gas at a pressure of 25. The properties of the steel are as follows: yield stress in tension is 1000; yield stress in shear is 440 and modulus of elasticity is 208. The desired factor of safety with respect to yielding is 3,4.
Determine the minimum permissible thickness t min of the tank.
