modeling fluid in pipe

In modeling fluid flow in a pipe, when do I need to see the fully developed flow? (either of laminar or turbulent regime)
Do I need specific length in inlet or outlet?
What is the criterion for that?
I was thinking that if after any modeling there wouldn’t be any circulation (which cause back flow) in openings the length is enough (either of inlet or outlet), is it true?

I have a problem like yours. I want to simulate laminar-turbulent transition pipe flow through LES model in FLUENT 12. I want to simulate fluctuation ( pressure and velocity ) at the antrance region and want to see the laminar and transitional region.This is my thesis study.
I dont know how can manage this one through LES model.
If you have any information about, can you help me.
thanks to you
