Hello
I have to find out pressure difference at INLET and OUTLET for flow through a rectangular duct. I am using pressure-outlet conditions.
I check pressure values in reports > surface integrals > area-weighted average > pressure at inlet and outlet.
Pressure at outlet comes 0 and inlet pressure comes out 64 kPa. And NET pressure comes out 32 kPa.
So is NET pressure value the pressure difference ?

The difference is 64 kPa (inlet - outlet).
The NET value is the area-weighted average for both surfaces TOGETHER, i.e., since both surfaces seem equal, (64 + 0)/2 = 32 kPa.
