if it was gauge pressure wouldn't it be higher by two atmospheres. the for eg. 0.9+1.0 for a barg of 1.9 + external atmosphere of 1.0 for a 2.9, and that would be way to high for any system to handle. seems it would then be a bara cap rating against the external elevation pressure.
I'll start by saying I'm new here, but have found many help full tips over the last two years when searching the net. thanks.
the other day I got to thinking about something that seems simple on the outset but didn't solve out that way. cooling system pressures and rad caps.
rad caps are rated...
