AWWA D103-97

AWWA D103-97

(OP)
My first pass with designing bolted steel tanks per D103. Code book has limited information. Would like several references for related design books. One specific question, Equation 1, Page 9, units don't match. I added conversion .433 to get balance. Wall thickness result appears much greater than I am accustomed to on another tank design program that I have used for many years. Thought and comments appreciated.

The 2.6 is actually 62.4 lb/ft^3 / 12 / 2.  The / 2 is dividing the D by 2 to get R (which is for the hoop stress equation).  See if the equation's units make sense using the 62.4 lb/ft^3.  No "fudge" factor needs to be input.  Please respond with further questions.  I was the chief structural engineer for a bolted steel tank company in time's past.

In D100, D103, API-650, ASME Sect. VIII, a lot of the formulas do not use consistent units- see the definitions for the units to be used on input in each case.
