Doubts regarding the formula for calculating diameter when pvelite selects the ASCE standard and requires the calculation of the wind path factor.

Thread Content

The client is in Bangladesh, and according to the requirements of the design institute, the wind load multiplier for PVE cannot use the default value of 1.2; instead, it must be determined based on calculations related to the container. The calculation formula is as follows: outer diameter of the container + 2×insulation layer + 0.91 + maximum diameter of the equipment’s pipe outlet… Well, why does the maximum diameter of the equipment appear at the end? How can calculating the radial dimension result in an axial dimension appearing as well? Later, after looking up some information, I found that the second edition of Badnar’s manual for pressure vessels contains very similar formulas for calculating the dimensions affected by the vessel shell. However, since it was a sample calculation and the origin of this formula was not mentioned earlier, nothing more could be done; but it was still clarified that the original formula was correct. Although the problem has been solved, I’m still confused. I’ve come specifically to solve it.
