“here’s a Sankey diagram of the energy balance in an industrial compressed air system. The factory is situated in Ireland (not too far from Co. Tipperary!) [Note from Phineas: this is where Cpt. Sankey was born]. The work is detailed in: Eret, P., C. Harris, G. O’Donnell & C. Meskell, A practical approach to investigating energy consumption of industrial compressed air systems. Proceedings of the Institution of Mechanical Engineers, Part A (Journal of Power and Energy), 2011. DOI: 10.1177/0957650911423173″

A nice, simple, clear diagram. Thank you. If other readers have Sankey diagrams to share, please send them to
