Hello,

I think you should use static pressure. I'm not quite sure about its definition, but for fluent absolute pressure is "operation pressure" + "gauge pressure" (http://www.engres.odu.edu/Applicatio...ug/node332.htm). And assuming that gauge pressure is in fact dynamic pressure, I then believe that it's not the pressure you're looking for.

Just check if the results for static pressure is also relative to the operating pressure or they're absolutes.

I hope I could make my self clear - and I'm not sure about that.

My best regards, Victor
