ASME STS-1 2006 Example E-3

ASME STS-1 2006 Example E-3

ASME STS-1 2006 Example E-3

(OP)
I have been working through Example 3 of STS-1 2006.
I have worked through up to the point of producing w(z) in Table E-1.
The output in the table is 12x the answers I get.
That makes me wonder if the "12" in the denominator is correct in equation 4-2.
I worked through the units.
"I(bar z)" is unitless, qz is lb/ft^2, D is in feet.
Cancelling units produces lb/ft.
Which is the correct units.

But should the "12" really be in the equation?
Or, am I missing something incredibly simple as is usually the case.

Thanks

Nevermind, "D" is in inches.
I got it now.
"D" is feet every where else in this spec, but here, it's inches.
