WebTHIN CYLINDERS. If the thickness of the cylinder is less than 1/10 to 1/15 of the diameter of the cylinder, it is treated as the thin cylinder. It is assumed that the stresses are uniformly distributed through out the thickness ofthe wall. 'Hoop stress’ or ‘Circumferential stress’ is given by. ‘Longitudinal stress’ is given by. WebA cylindrical pressure vessel is fabricated from steel plating that has a thickness of 20 mm. The diameter of the pressure vessel is 450 mm and its length is 2.0 m. Determine the maximum internal pressure that can be applied if the longitudinal stress is limited to 140 MPa, and the circumferential stress is limited to 60 MPa. Solution 136
