2 - Efficiency homework

The Sankey diagrams must be
  • neat
  • to scale
  • complete with three full labels on each one.
I would rather 4 neatly completed questions that 8 sloppy ones! If they are not neat enough, you may be asked to do them again.

Stop after 30min

ALTERNATIVE HOMEWORK;
Although every question in the task above contains a calculation of efficiency, if you know calculations is normally something you need time to practice you may choose this alternate task;
  • Complete 4 Sankey diagrams on the original homework (so complete up to question 5 as I did the first one for you)
  • STOP

  • Using my examples complete parts b) onwards for the worksheet "1 - Efficiency Collins Worksheet" in the same lesson folder.

  • Answers to this sheet are on the content library, so you can check as you go

  • You must attempt Q2-5 on the original homework first.
