A process vessel $10ft$ inside diameter and $25$ftfromtangentlinetotangentlineheight

is required to process petroleum hydrocarbons at $130$ psi and $250F.$ The steel used

in fabricating the shell and formed heads is SA$-285$ Grade C$,$ and joint efficiency of

$0\mathrm{.}85.$ The dished head has a radius of $36$ in and a knuckle radius sf $4$ in$.$ The design

of the shell and formed heads should be according to code specifications. The

corrosion allowance is $\frac{1}{16}$ in$.$ Determine the total weight of the shell and formed

heads if the density of the steel is $490l\frac{b}{f}{t}^3.$ Select suitable formed heads for the

vessel and determine their thickness and dimensions.
