API 650 Appendix E - How do you figure"Nh" ?
(OP)
I am looking to get some confirmation on the calculation for (Nh - the Product hydrostatic membrane force) in API 650 App. E
I think it is the head pressure at the elevation in question divided by the thickness at that elevation.
(Head Press/shell thk.)
My second guess is that it could be
(Head Press/circumference)
Thanks in advanced.

Nh=PR = 62.4(H-1)G/144 x D/2 x 12"/ft = 2.6(H-1)DG
