problems about pressure inlet
I see from the Fluent 6.2 User's Guide that:in the pressure inlet, Ps'=Ps-ρgx,in which Ps is the static pressure,Ps'is the pressure.Can anyone tell me what is x present?Is it the depth of the water?

And meanwhile I have another question to ask for your help.We all know that the Bernoulli equation is Z1+P1/(ρg)+α1*V1*V1/(2g)= Z2+P2/(ρg)+α2*V2*V2/(2g)+hw,what I want to know is how to consider the effor of potential energy(Z1 and Z2) in our CFD caculation?

Thanks very much for your help!

how can icalculate static prasuure of fan in duct
dear sir i wold like to know ate lao os calculation the static pressuer of fan which deliver the duct in airconditioning system

Re: how can icalculate static prasuure of fan in d
The static pressure of a fan is: psf = ps2-pt1

where: psf= static pressure of a fan

ps2= static pressure at fan outlet

pt1= total pressure at fan inlet

I don't know if this is exactly the definition you need, but i think it could be helpful.
