Odds and ends

Dear class,

Solutions to HW8 and 9 are posted on the course website. In addition, solutions to the problems worked in the review session last night are posted there. If you have not received your graded HW8, please see Avi (Engineering II 3218). Due to HW9's due date of last Friday, we probably won't be able to get these graded before the final exam, but you should be able to review these problems using the posted solutions.

In preparing for the final, keep in mind this general problem solving strategy:

1. Make diagrams and/or tables to organize problem information.
2. If a problem involves many steps, break it into individual processes.
   
3. To each step, apply the first and second laws, choosing the version (closed or open) as appropriate.
4. Identify any quantities that are constant or zero and use these to simplify the first and second laws.
5. Determine any quantities that you can solve immediately: Q, W, DH, DS, DU, etc.
6. Use substance-specific data to solve for the remaining quantities: charts, steam tables, PVT EOS, Cp models, generalized correlations, etc.

This strategy should carry you through almost any thermodynamics problem and will, at the least, earn you partial credit.

Good luck on the final! I've enjoyed teaching you all this quarter and hope you continue to stay in touch as you progress through the curriculum,

Cheers,
MSS
