Ran in 4 of the last 7 terms. Winter 2027: scheduled, 2 lecture sections. Spring 2027: schedule not out yet.
Introductory application of associated physical and chemical theories for unit operations involving separation, fluid movement, and heat transfer. Material balances for single-component and binary systems involving vapour-liquid, liquid-liquid, and liquid-solid phase equilibria. Energy balances for mechanical, non-reactive, and reactive systems. Introduction to problem-solving techniques for chemical engineering unit operations.

Took this W2026 and in general found it to be a very well structured and paced course. Whereas CHE100 feels all over the place and random, CHE101 feels organized and concise. I think the majority of this lies in Peter Angelo's skills as a professor; he's seriously phenomenal at what he does. First half of the course is just phase equilibrium (mostly review tbh) only new content being different types of diagrams and graphs you have to interpret (which is fairly simple, kinda boring). After midterms it really begins to fall into a nice groove with energy balance which I found to be very interesting, with many applications in chemical engineering. Its much more interesting than mass balances…

There are two components of this course (though I think they are separating them starting from next year but anyways). First is the lecture component, where pre-midterm is basically phase equilibrium and reading diagrams, so if you struggled on phase equilibrium in CHE 102, review the topics. The post-midterm content focuses on energy balance. It is not too bad for me, but the calculation is sometimes tedious (did 3 integrations for the final on one question). Second is the lab component, where it is basically a different course (I think this is the reason why they are separating them), where 4 labs are done on various topics. The lab report is tedious, but it is a good time to practice to…

S25 with Peter Angelo. First half (phase EQ) was not too bad, second half (energy balances) took some getting used to but the questions all follow kind of the same process (like the MB questions in CHE 100) so if you understand the practice questions, you should be good on the exams

the questions before midterm can all be solved by mass balance(which you've learned in che100) but tbh energy balance is difficult, so i got a really low mark in my final test...

Overall pretty much meets all expectation. Difficulty level could definitely be high but it really just depends on the prof. The only thing is expect problems to take quite a long time.
For the lab portion the experiments were sort of useless but were good practice at righting reports.Sep 2024 · liked itOn UW FlowRemove this
