Except you leave yourself a little wiggle room incase you need a
little extra thickness for thermal, wind or gravity stresses. You can
figure the thickness needed to resist pressure only directly, but for
the other stresses you need to assume a thickness to figure the
stress, which you compare to the allowable.
