[Solved and can be disabled] Regarding the hydrogen vent flow rate

Hydrogen should be vented into a sealed space; how does it come into contact with air then?
Hydrogen has too low a density, and it is not possible to prevent air from entering the pipeline after venting; therefore, a flame arrester should be installed 1 meter at the end of the pipeline where venting takes place.
I’ve learned it, thanks to the friend above: lol
The Soviet standard was within 8 meters, while the American standard was within 16 meters. Design institutes are usually located at around 10 meters.
Explanations to the design specifications for hydrogen stations 12 Hydrogen pipelines 12.0.1 The maximum flow rate of hydrogen in carbon steel pipes shall comply with the requirements specified in Table 12.0.1. Design pressure (MPa) Maximum flow velocity (m/s) >3.0 10 0.1~3.0 15
I have uploaded the specifications for the hydrogen station; those who need them can visit http://bbs.hcbbs.com/thread-145823-1-1.html
Study the standards carefully – the design specifications for hydrogen stations should help you find the answer
Well, thank you. The specifications for floor 8 came as garbled text after I downloaded them. Last edited by Lin Xuefeng on 2008-1-25 08:20.]
Floor 7 lists the flow velocity limits in the pipes under different pressures, among which"
