10/7/2017 · From the entrance point up to the perfect parabolic shape it is known as entrance length or entrance region. It is the distance travelled by the flow before it becomes fully developed. beyond this region we will get a fully developed flow. Also at the starting cross section of fully developed flow two boundary layers of pipe meet

1/7/2010 · Not really (at least IMO). Rather, with "fully developed flow" you should think that viscous effects have spread throughout the fluid in the pipe, i.e, that the "inviscid core" has disappeared. Think of a jet of water entering a pipe. Close to the entrance region (on the inside of the pipe ...

The need for flow conditioning, and hence, a fully developed velocity flow profile is driven from the original determination of Cd which utilized fully developed or 'reference profiles' as explained above. Conversely, the turbine meter operation is not rooted deeply in fundamentals of thermodynamics.

An analysis is presented of fully developed laminar flow in an eccentric annulus. An exact solution for the velocity distribution is presented. From this solution may be obtained expressions for local shear stress on the inner and outer surfaces of the annulus, friction factors based on the inner and outer surfaces, and the overall friction factor.
