hvem10 is on a distinguished road
When I calculate the pressure drop I normally use mass weighted average on two surfaces. The pressure drop is then the difference in the total pressure.
I now have a calculation where the total pressure increases !! That can not be correct, that means the energy level should increase.

But how valid is this approach, does it have any influence if I have reversed flow on any of the surfaces.
