Differential static pressure

From Ron Wroblewski 10/10/2024

Another "issue" was that when we were developing the fans module we said there's a binary choice of using a)Fan Static or b) fan total pressure. but two different fan vendor's quotes we evaluated for this project used a third method, which is differential static pressure.... static pressure at outlet minus static pressure at the inlet (without the correction for the velocity pressure at the inlet) Took a bit of 'splainin' on my part to say why I was leaving the velocity pressure as zero. but at the same time, this is such a rare occurrence I'm not entirely convinced it's worth changing anything, either, but I thought I'd mention it.
