Stagnation pressure

SDF — 2/23/2007 11:34:52 PM (archived)

What's important is the pressure differential, not that all the air going in, exits as well. Alot of it may in fact flow around the structure. In fact, if some didn't flow around, I'd be reluctant to say that the maximum pressure difference had been achieved.
