IB Physics SL A.3.3 Sankey Diagrams Question Bank

Practise calculating efficiency and losses from Sankey diagrams, then drawing proportional labelled arrows for energy and power transfers.

Exam points

Read Sankey arrow widths to calculate useful output, wasted power or efficiency from the labelled energy flows.
Construct proportional, labelled Sankey arrows from input and output power, showing direction and losses.

[Maximum number: 3]

On the grid, sketch a labelled Sankey diagram that represents the energy transformation in this OWC.
