E = joint efficiency for, or the efficiency of, appropriate
joint in cylindrical or spherical shells, or the effi
ciency of ligaments between openings, whichever is
less.
For welded vessels, use the efficiency specified in
UW-12.
For ligaments between openings, use the efficiency
calculated by the rules given in UG-53.
P = internal design pressure (see UG-21)

S = maximum allowable stress value (see UG-23 and the
stress limitations specified in UG-24)
t = minimum required thickness of shell
