A thin spherical pressure vessel is subjected to an internal pressure of 4 N/mm². The mass of the empty vessel should not exceed 125 kg. If the factor of safety is 3.0, design the pressure vessel with the objective of maximizing the gas storage capacity, out of the following materials : Material Ultimate Tensile Strength Mass Density Su N/mm² p, kg/m Low Alloy Steel - 15 Cr90 M055 500 7800 Aluminium Alloy - 74530 250 2800 Copper Alloy - Cu...
A triple riveted butt joint with equal double cover plates (zig-zag riveting) is used for the longitudinal joint of a Lancashire boiler of 2.5 m internal diameter. The working steam pressure is 1.12 N/mm2 and the efficiency of the joint is 85 per cent. Calculate the plate thickness for mild steel of 460 MPa ultimate tensile strength. Assume ratio of tensile to shear stresses as 7/6 and factor of safety 4. The resistance of the rivets in double shear is...
A spherical pressure vessel, with a 600 mm inner diameter, is welded from steel plates. The welded joints are sufficiently strong and do not weaken the vessel. The plates are made from cold drawn steel 20C8 (Sut= 480 N/mm2 and Syt = 250 N/mm2). The vessel is subjected to internal pressure, which varies from zero to 10 N/mm2. The expected reliability is 50% and the factor of safety is 3. The surface finish factor is 0.8. The vessel is expected...
A cylindrical pressure vessel of 250 mm mean diameter and 6 mm wall thickness is fabricated from a 1.2 m length of spirally welded pipe AB as shown. Tank gauge pressure is 4 MPa and centric axial forces P and P1 of 240 kN act through rigid end plates. Determine: (a) Net longitudinal and hoop stresses. (b) Normal stress acting perpendicular to weld and shear stress parallel to weld (show sketch of Mohr’s circle). (c) Determine the Factor of Safety...
2.) A large spherical tank 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. Determine the required thickness (to the nearest 4 inch) of the wall of the tank if a factor of safety of 3.5 with respect to yielding is required. Next, if the tank thickness is 2.25 in., what is the maximum internal pressure. (Problem 8.2-3)
