I need the whole solution for this question! Thanks 2.6 Calculate the safe working pressure for a 2 m diameter spherical container, with wall thickness 15 mm, if the ultimate tensile strength of its material is 420 MPa, the factor of safety is 6 and the efficiency of welded joints is 90%.
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...

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 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 compressed air vessel has an inside diameter of 2 m and a plate thickness of 12,5 mm. If the tensile stress induced in the plating is to be limited to 100 MPa, calculate for both the longitudinal and circumferential seams the pressure necessary to induce this stress. Take the longitudinal and circumferential joint efficiencies as 80% and 50% respectively. What would the actual allowable 2 pressure be? [l MPa) A compressed air vessel has an inside diameter of 2...
