I would like to ask how to calculate the size of the openings for the exhaust devices on the head of a deaeration tower.

Generally, a device similar to an manhole is installed on the head of the deaeration tower; some versions use DN400 connections, while holes are made in the flange cover to connect pipes of DN50, 80, or 100 sizes. How is this exhaust hole size calculated, and when are DN50, 80, and 100 sizes used? ? ?
It is related to the designed exhaust volume of the deaerator; the exhaust port of an atmospheric deaerator can be slightly larger； Pressure deaerators require calculation; if the value is too high, too much steam will be released, while if it is too low, oxygen and other gases won’t be removed
Could you give an example calculation? Thank you.
