Thermodynamik

State, work and heat, both laws, entropy and the cycles — with the steam tables and the sign conventions that cost marks. Placeholder content.

10 lessons · about 3.3 hours · Second-year engineering, preparing for the thermodynamics examination

The syllabus, mapped

  1. 01Systems, state and properties — The vocabulary every problem is stated in.
  2. 02The first law for closed and open systems — The bookkeeping the paper rests on.
  3. 03Pure substances and the steam tables — Reading the tables right is half the marks.
  4. 04The second law and entropy — Where most people lose marks, so it gets the most time.
  5. 05Gas and vapour cycles — Otto, Diesel, Brayton and Rankine as applications.

The first lesson is free. The other 9 (3.3 hours in all) cost $8.42 bought together.

Or $1.70 a lesson one at a time, or $20.00 a month for Minimal — cheaper once you take more than ~11 lessons a month.

Quarter zero: a supply shock: costs rise at every level of output, so short-run supply moves up and left. Output is below potential by 3.2% and inflation is at 3.5%. Nothing has adjusted yet — this is the picture the textbook draws second.
