4D; 
Often one changes the inside diameter, D,, 
of a cylindrical shield without changing its 25 
thickness, ¢. This nomogram gives the frac- 
tional weight change, f; new weight is 1 +f 
times the original shell weight. Weight of 
end plates is not included, of course. 
EXxaMPLE: Shell with D; = 10 in. andt = 2 
in. is enlarged to D; = 20 in. Nomogram 5 
gives fractional weight change as 0.82; new 
weight is 1.82 X old.
