Hy there,
I think absolute pressure is positive. pressure can be negative if it is gage pressure. For analyzing the pressure, you can try Cp (coefficient of pressure)..
hope it helps

-mAx- will become famous soon enough
absolute negative pressure may show cavitation genereration (although negative absolute pressure is physically impossible)
