Procedure 2-8 Design of Intermediate Heads

El = modulus of elasticity at temperature, psi S = code allowable sttess, psi Hd = hydrostatic end force, lb Pi = maximum differential pressure on concave side of head, psi 

Pe = maximum differential pressure on convex side of head, psi 

E = inside radius of hemi-head, in = 0.9D for 2 1 S.E. heads, in = KD for ellipsoidal heads, in = crown radius of E D heads, in
