What is Sankey diagram?

#basics #thermodynamics


Ans: Sankey diagrams are a type of flow diagram in which the width of the arrows is proportional to the flow rate of the depicted extensive property.


Sankey diagrams can also visualize the energy accounts, material flow accounts on a regional or national level, and cost breakdowns. The diagrams are often used in the visualization of material flow analysis.

Sankey diagrams emphasize the major transfers or flow within a system. They help locate the most important contributions to a flow. They often show conserved quantities within defined system boundaries.
