Equation for calculating the limiting stress within a repair area on the shell of a tank, which shall not exceed 7000 lbf/in^2.
S = (2.6 H D G)/t
where:
S = shell stress in lbf/in.2,
H = tank fill height above the bottom of repair or alteration in ft,
t = shell thickness at area of interest in in., D = tank mean diameter in ft,
G = specific gravity of product.
