identify an example of Constructal law (branched structure). The context could be the natural world, but could also be a human construct (i.e. technology, economics, transportation, etc.). include an image illustrating the branching structure and a very brief description of what the structure is, and what is flowing through it.

Do an online search for a research publication in which an empirical scaling law is identified. Write a short paragraph explaining what the empirical scaling law means.
