I'm currently designing for an addition to an existing pre-action system. This existing pre-action system (with three existing pre-action valves) and is connected to a 130 cubic-foot nitrogen cylinder.
How can I calculate if this much nitrogen would be enough if I added in another preaction valve?
Do I need to calculate the volume of all the pipes downstream of the preaction valve?
What other information should I gather?
How much percentage of the piping downstream of the valve needs to be filled with nitrogen?
Thanks in advance.
