Regarding the suction pipe on the circulation return water pipeline of the synthesis furnace

The diameter of its return water pipe is DN200. A suction pipe is to be installed on this return water line to connect to the atmosphere (to prevent siphoning effects); the drawings show that the suction pipe should have a diameter of DN25. I’m not sure if this is sufficient, as the suction pipes used in previous synthetic furnaces were DN50 in diameter. Please advise! # hcbbs
The drawings should show the results calculated by a qualified design firm. DN25 pipes should be large enough; on our circulation water pipelines, DN250 pipes work just as well with DN25 pipes, and no abnormal issues have occurred.
As a supplementary note, the height of the return water pipeline is 1** meters; the return water pressure is 0.25 Mpa, while the supply water pressure is 0.35 Mpa.
The height is 1**m, why did it turn into an asterisk?
High is seventeen point five meters.
