25 Variables:

26 nt [in]= tf-Corr ~~thickness with corrosion allowance removed 0.118-0.039 = 0.079

27 D [in]= Do-2*nt ~~ID with corrosion allowance removed 37.441-2*0.079 = 37.283

28 L/r = L/IKR 18.72/1.969 = 9.510

29 M = 0.25*(3+sqrt(L/IKR)) 0.25*(3+SQRT(18.72/1.969)) = 1.521

30 Ro [in]= L+tb 18.72+0.118 = 18.839

42 App. 1-4(f) calculation is not included on this sheet

43 Nozzles may be subject to a smaller required thickness depending on location in the head.

44 Only the knuckle required thickness is calculated on this sheet

45 Heads may be subject to stress relief if large elongation occurs - UCS-79(d), UNF-79(d), UG-37(a)(1)46 The UG-16(b) minimum thickness requirement has not been taken into consideration here.
