And/or a surge valve, leaks at low volume and slams shut at higher volume.
I use this for a LOx vent on test stands.
Passive and maintence free.

Hi,
After having a failure on the primary ejection charge because the hole was
too big (back up charge worked). I started to search the web for a vent
hole calculator (not av bay). But I couldn't find one. Does anyone have a
formula or calculator for this? The body tube is 610mm tall, 98mm in
diameter and the hole size was 6mm (24', 4' and 1/4' roughly).
