Sankey Builder
Enter the energy going in and each energy transfer coming out. The arrows are drawn to scale. Leave one value blank and the builder works it out using conservation of energy.
Examples
Energy in
J
Energy out
Drawing
Each small square is one unit of the scale, so you can count squares to check the width of every arrow.
