A cylindrical steel pressure vessel with mean diameter 1.5 m, length 4.0 m, wall thickness 8.0 mm and closed ends is subjected to an internal pressure of 1.2 MPa. Find the circumferential and axial strains and hence determine how much the volume inside the vessel increases due to pressurization. (Esteel = 210 GPa, νsteel = 0.30). Assume that the ends remain flat.
