Flow between parrall plates entry length formual?
I am trying to compare the solution of the problem of laminar flow between parrallel plates with pressure gradiance using CFD pacakges and theory. I want to know where can I find the formula of the entry length (the length at which the flow reaches it's full development state). I found this formula for pipes in many reference of fluid mechanics but I didn't for the parrallel plates. If anybody can help I would be gratefull. S. S. Mudathir

Thanks, and no need to reply, I got the answer
Thank you very much, no need to answer this question because I got the answer. It is found in shilchting.

you can estimate in a very simple way, just use the laminar boundary layer law delta=delta(x) from some of those in literature and fix the condition delta=H/2 to estimate the corresponding x.
