Pressure Drop, Electronic Housing

I have a box with an air inlet (defined as inlet staticpressure) and an outlet that will be a fan (defined as outlet fixedvolumetric flow rate). I need to find the pressure drop at theoutlet to determine the prospective fan performance. I can usesurface goals at the inlet and outlet, and use those results for anequation goal to find the delta but:
The choices for surface goals are Static Pressure, Total Pressure,and Dynamic Pressure. Also the choice of Min, Max, Average, or BulkAverage must be selected.

I am somewhat confused as to the defintion/selection of correctgoals to determine the pressure drop. Any help would beappreciated.SolidworksFlow Simulation
