Abstract : The paper corrects, summarizes, and expands the author's concepts in previous papers in this series. Hierarchical systems of flow show many characteristics which derive from the necessity of transmuting energy from potential to kinetic or kinetic to potential, on surfaces. The principle of least work applied to flows over hexagonal areas appears to explain empirical regularities in hierarchical systems. The principle of least work applied to mixed hexagonal hierarchies may be the basis for allometric growth. (Author)
