A cylindrical vessel of 3 m outside diameter and 8 m length is supported by 4 lugs. The vessel is filled with fluid having density of 870 kg/m³ up to 5 m height and is being operated at 1.5 MN/m² pressure (g). It is covered with flat heads from both ends having weight of 12 kN for each head. Corrosion allowance is 2 mm. It is class 2 vessel having double welded butt joint with full penetration for all joints. The vessel is made of IS: 2041-1962 20Mo55 and its design temperature is 450°C. The wind pressure on the vessel is 0.9 kN/m². The height of the vessel from the foundation is 1 m. Height of bracket from foundation is 5 m and end diameter of anchor bolt circle is 3.1 m. The steel channels are utilized to support lugs. Given: Allowable stress of horizontal base and gusset plate = 100 MN/m²; allowable stress of channel = 150 MN/m², density of shell material and Poisson's ratio of 7600 kg/m³ and 0.3, respectively. a) Standard thickness of shell b) Compute the minimum thickness of horizontal and gusset plates for I = b= h = 150 mm and 0 = 60" c) Determine the area of cross-section of channel column for section modulus of column as 200 cm³. Also suggest the suitable size of column.

If we not consider the wind load than we will eliminate the pw right in this video u sad that eliminate the Wmax
Very nice content
Hello mam, I need to ask that if pressure vessel is on legs only without any bracket or leg then how to design itm
Thank you so much ❤
Thanks
Mam there is one doubt
Madam, i have a boubt
What is mean by diameter of anchor bolt circle
Is there any approximation for that
hello can i ask the reference book? what is the name of the book?
