Heating processes that map heat balance items as proportional band widths in a diagram are known as__________________?
Show answer Hide answer
Answer: C. Sankey diagram
Explanation
A Sankey diagram graphically depicts thermal energy balance flows. It represents heat inputs and losses as proportional band widths. The width of each flow band directly corresponds to the magnitude of energy. Named after Captain Matthew Henry Phineas Riall Sankey, these diagrams visualize energy. Energy conservation principles ensure total input widths equal total output widths. Complex thermodynamic systems become easily understandable through visual band scaling.
Energy auditors use Sankey diagrams to present industrial furnace heat losses clearly. Plant managers identify major inefficiency areas instantly by viewing wide loss bands. These diagrams communicate technical energy data effectively to non-technical stakeholders. Ostwald charts are graphical tools used to compute combustion air excess or deficiency. Cox charts are specialized nomographs used for vapor pressure temperature correlations. None of these is incorrect because Sankey diagram is the correct matching term.
