Chris Michalski Jan 26, 2016 3:37 PM (in response to Chris Weindorf)Just to verify, you do have gravity turned on and in the correct direction?

Chris Weindorf Jan 26, 2016 3:41 PM (in response to Chris Michalski)Yes, gravity is turned on in the Y direction.

Chris Michalski Jan 26, 2016 3:48 PM (in response to Chris Weindorf)Looking again, are you really interested in setting the Total Pressure at both ends? I usually work in gauge so I'd have to think on that...

Amit Katz Jan 27, 2016 9:57 AM (in response to Chris Weindorf)Total pressure = pressure + dynamic pressure, so I don't think you'd be wanting to use that in this case.
Doing some quick back of the envelope your numbers are pretty confusing. I'm assuming you're using water. The hydrostatic pressure required to raise water to a height of 14 ft is approximately 6.1 psi (http://www.wolframalpha.com/input/?i=density+of+water+*+9.81+m%2Fs%2Fs+*+14+ft+to+psi ), so where does that leave head for moving your flow?
On the other hand, if your fluid is air then the head loss is less than 0.008 psi, which means nearly all of your 2 psi difference is dynamic. If that's the case, then for air the expected velocity at the outlet would be around 480 ft/s (sqrt(2*2psi/density of air)  WolframAlpha )
