Next, you are ready to define the shell courses.
-
Select the Shell Courses tab.
-
Specify each shell course as 10 foot in the Height boxes. By default, the software calculates and enters the shell course Height value by dividing the Tank Shell Height by the Number of Shell Courses. However, you can edit these values as needed.
-
Type 0.3750 for the first course thickness.
-
Type 0.3125 for the second course thickness.
-
Type 0.2500 for course thicknesses three through six.
TANK populates the Material, Design Stress, and Hydro Test Stress boxes based on the input data you enter on the Tank Data tab.
