Homework Statement
The problem is to calculate the required thickness of the shell of a pressure vessel, given that the design pressure P is 400 psi, the strength S is 15800 psi, the corrosion allowance CA is 1/8"and ##R_{design}## is to be found by iteration.
Homework Equations
##t_{req}=\frac{P(R_{design} + CA)}{S-(0.6P)}##
To account for corrosion, CA is added to ##t_{req}##
##t_{CA} = t_{req} + CA##
Using ##t_{CA}## , a standard size is selected, denoted ##t_a##
The Attempt at a Solution
Guessing ##R_{design}##, I solved for ##t_a##
Re-arranging the equation to solve for P,
##P=\frac{tS}{(R_{design}+CA)+0.6t}##
and using the guessed ##R_{design}## value with the ##t_{req}## value found above, I should check if P>400psi?
