Default Periodic Boundary Cond.

I need to solve fully developed flow between two plates. My concern:

If i don't want to take my computational domain so long (I mean along the flow), how should i set my boundary condition at inlet or outlet.

Of course i need some pressure drop, i.e. p_inlet is NOT equal to p_outlet (p=pressure). What about velocities? i.e. what about u_inlet and v_inlet?

Does it matter I set u_inlet = u_outlet rather than the case setting u_outlet = u_inlet.

I am using a compressible code, so what should it be the b.c. for the temprature?

Thanks alot
