PG-35 - Opening in Flat Heads 1

[antoinealt]

Hello,

PG-35 seems to be dealing with flat heads with a SINGLE opening. What about flat heads with MULTIPLE openings?

Should I calculate an equivalent single opening with the same surface area as the multiple opening areas added up together?

Thank you for the help.

Antoine.

Well ... I just had to turn a few pages to go to PG-38.

But any suggestion/tip/idea is still welcome.

Thanks.

Antoine.

You need to read and follow PG-32, first, and determine if you meet any of the criteria for multiple openings. There are size limitations and openings that have inherent reinforcement versus those that do not. This is spelled out in PG-32, which also references PG 33-39.
