6. Background Energy transferred Side question Are heat exchangers important?

7. Background Energy conversion to work

8. Background Energy conversion to work

9. Background Energy conversion to work

10. Thermodynamics Energy conversion to work Heat pump Carnot, for example Heat in Heat out Work

11. Background Energy conversion to work Heat in Heat out ? Work

12. Background Energy conversion to work

13. Needs Air-cooled condensers They use Cooling towers

14. Needs Cooling towers --- quite a few

15. Needs Cooling towers 40 across!

16. Needs Cooling towers 3 deep!

17. Needs Cooling towers 2 banks!

18. Needs Cooling towers 40 across x 3 deep x 2 banks = 240 cooling towers!

19. Question Are cooling towers important?
