2.051  Introduction to Heat Transfer

HW Grades and Thank You

Hi all,

I've posted all your homework grades. If you have a zero in something, it means you didn't hand it in. If that's incorrect, let me know. Also let me know if you had a problem set or quiz regrade and it wasn't updated.

I also want to take this opportunity to thank you all for a wonderful class!

I am really blown away by how quickly you guys learned the material and how well you applied that knowledge. Looking at your psets, and your final exam, I really have to say that you guys should be proud of yourselves. Great job!

Also, I'm sure some of you know that this was my first time teaching. I hope you guys had a fun time and that I was able to help you guys understand and appreciate heat transfer as much as I do.

As my first class, I'll never forget you guys, and I hope you guys go on to have very prosperous careers and happy lives.

Happy holidays and thank you again!

All the best,

Tomas

Final Exam

Hi Folks,

It's final exam time! A few reminders and tips for the exam:

1) The exam is a 3 hour exam. The exam starts at 9:00am on Thursday December 19 in Walker. Please arrive early to make sure you get all the allotted time.

2) Remember to bring:
- Two pages (double-sided, 8.5"x11") of notes. (Hand-written, typed, xeroxed are all ok)
- A (non-internet enabled) scientific calculator. Calculators on phones, ipads, tablets or other internet enabled devices are NOT allowed.
- Printouts of the correlation handouts including: dimensionless groups, Nu correlations for internal and external flow, boiling, condensation. (You may annotate these pages if you'd like.)

3) Remember we are grading you on the concepts listed on the front of the exam. Every concept is worth the same number of points regardless of how long it takes to do the problem. We highly recommend reading through the exam and doing the fast easy parts first! Then go back to work through the longer, trickier parts of the questions. The concept list for this exam is:

Derive and apply conservation laws
Problem 1 (3 pts)
Problem 2 (3 pts)
Apply appropriate rate equations
Conduction (3 pts)
Convection (3 pts)
Radiation (3 pts)
Select and apply appropriate heat transfer correlations
Internal and external flows (3 pts)
Natural convection (3 pts)
Boiling (3 pts)
Algebra, integration, and sanity check (3 pts)

Short answer questions (9 pts)

In budgeting your time, we recommend that you spend an hour or less on the short answer questions.

4) Hint: The theme of this exam is FEET!

See you all on Thursday!

Material Notes

Hi All,

I've just posted my (kinda long) material notes.

IMPORTANT! Please note that the radiation resistance that I gave you in lecture should have an A for area on the bottom. R_rad = 1/(4*epsilon*sigma*T_mean^3*A)

Best,

Tomas

Subject Evaluations!!

Hi All,

It's very important to us that every student evaluates the course. If you guys don't, then we won't know what was good or bad.

We've put a lot of time into preparing materials for the class, so we ask that you guys take ten minutes and fill out the evaluation.

They close on Monday morning, so please do so today, tomorrow, or Sunday!

Thanks very much!!

Best,

Tomas
