Where: t= Plate thickness for course under considerationhp= Liquid hieght from top capacity level to bottom of course under considerationD= Nominal diameterG= Specific gravitys= Allowable design stressE= Joint efficiency

CA= Corrosion allowance

Tank #D= 14.50 ft 4400 mmG= 1.0s= 22040 psiE= 0.85

CA= 0.039 in.H= 21.82 ft 6650 mm

Tank hieght is 6650mm or 21.82'. This suggests 3 shell courses as follows: course 1 @8', course 2 @8', course 3 @5.82' Top capacity level is tcp= 21.82 6650 mmThen hp= course 1= 21.82 course 2= 13.82 course 3= 5.82

The calculated plate thickness requirements are as follows (the min allowable is 3/16"):

Course 1= 2.6hpDG= 0.043686 in. Min.plate= 0.18750sE

Minimum plate plus corrosion allowance is 0.2268701 in. or 1/4" plate
