I think fluids travel faster near the center of pipes and tubes better than at the edges because they are able to travel much faster, and smoother in the center rather than the edges because the fluids have to turn, which could cause the rest of the incoming fluids to stop, which would make it much slower when traveling through the edges than through the center.
Scientific journals are a place for the scientists to share the results of their work.

With the journals, they can instead focus on furthering our knowledge, and not repeating the basic experiments.
