1. A process vessel is to be designed for the maximum

1. A process vessel is to be designed for the maximum operating pressure of 200 kN/m. The vessel has the nominal diameter of 2 m and length of 4 m. The vessel is made of IS: 2002-1962 grade 2B quality steel having allowable design stress value of 140 MN/m at working temperature. The corrosion allowance is suggested to be 2 mm for the life span expected for the vessel. The vessel is to be fabricated according to class 2 of Indian Standard specifications, which stipulate the weld joint efficiency of 85%. If the process vessel is to be provided with a conical head, having the half- apex angle 15, determined the thickness of the head. [5]
