Determine the mass of a pressure vessel made of 304 SS with 2:1 elliptical heads. The dimensions of the vessel are a diameter of 2.6 m and a length of 7.5 m (tangent to tangent). The design pressure and temperature of the vessel are 3.7 MPa and 450C. You should assume a corrosion allowance of 1/8 inch and that nozzles and manways will contribute an additional 15% to the mass of the vessel. In addition, you should assume that all welds are double-welded butt joints with spot radiographed examination
