Portfolio for Thermo
This is the time for a masterpiece.
Make a portfolio of 3 “problems”(one for each class goal, below) that you
invent and solve yourself - fi rst by fi nding something thermodynamic in the
world, then describing & solving it mathematically in “thermo” language,
and fi nally, extending it and improving it. Above - Harvest of sugarcane in
Brazil.
1

that exists you can
observe somehow
Describe it in
words and
models
Include appropriate
assumptions &
calculations
Extend and
Improve
What next? What
else?

Balances on systems &
cycles
1
PROPERTIES & VLE

calculations &
evaluations on 1 or
mixed chemicals

SUMMATIVE PROJECT, CHEG 310 THERMODYNAMICS
DUE MAY 9, 2023
Final Exam*
Do your own thing, show me what you know
Detailed Objectives
In more detail, you will:
Be able to state the fi rst and second laws of
thermodynamics and apply them in a variety of
situations.
Be able to perform energy and entropy balances on
a variety of idealized and real applications, in order
to calculate useful information such as the amount
of work one can gain from a given process (among
many other things).
Be able to predict the properties (such as boiling
point or dew point or gas volume) of a given
substance under given conditions, and state the
assumptions that go into that calculation.
Be able to predict the properties (for example,
generate a Txy or other equilibrium diagram) of a
mixture, know the limitations of that calculation,
and be able to use such calculations in the design of
separation equipment and other unit operations.
Be able to calculate the reaction equilibrium for a
given set of reactants under given conditions.
Be able to apply any of the above, alone or in
combination, to a complex, real-world problem, and
integrate its analysis with information from other
courses and outside research in order to design
something that is technically and socially
appropriate.
Be able to demonstrate comprehension of complex
thermodynamic concepts by explaining them in
terms that someone with less training can
understand.
Be aware of computational and properties resources
that help with the above calculations, where to fi nd
them, what their limits are, and how to use them.
Continue your practice of teamwork, oral
&
written
communication, open-ended problem solving skills,
and work on development of professional skills,
including job search and interview skills.

SUMMATIVE PROJECT, THERMODYNAMICS
DUE MAY 9, 2023
WHAT FORMAT?
I will accept your work as a written document, a graphically-rich
written document, as a presentation with audio, as a movie, as an
extremely well explained and formatted spreadsheet, as an extremely
well explained and formatted Hysys fi le, as something else I haven’t
thought of, as a combination of the above.
Every problem
must be
accompanied by the “problem cover sheet, ” as shown in the
appendix. If using video, all three problems can be one video.
At right, the control panel for the steamboat Natchez; at top,
petroleum refi nery on the Mississippi at sunset.
Appendix A: Grading Rubric for each problem
* There are performance levels
below
“minimal acceptable” that are graded accordingly.
Category
Superior Performance (~95)
Good
Performance
(~85)
Acceptable
Performance
(~75)
Minimum Acceptable
Performance (~65)
Technical
profi ciency &
Appropriate
level of
diffi culty (60
%
)
A problem that thoroughly uses
the appropriate outcome at a
rigorous level is defi ned.
Situation selected has
thermodynamic elements which
are clearly defi ned numerically;
good assumptions are made and
validated; the model that is
selected is a reasonable one;
values that must be invented are
likewise reasonable. References
are included. Calculations are
accurate.
Not SP
Not MAP
Problem is fundamentally the
same as one from HW/Quest/
In-class example/ other
common source or otherwise
trivial. Situation may be
tenuously thermodynamic;
assumptions are not well
validated, the model is chosen
more for convenience than
accuracy, numerical values
from poor sources or thin are.
May be some calculation
errors. References are few or
not included or not valid
sources.
Communication
profi ciency
(30
%
)
Communication is clear, succinct,
complete, organized. All
elements (writing, visuals, audio,
etc) contribute well to the story
and are executed with
profi ciency. Text and solution of
each problem should be 1-3
page equivalents of info.
But closer
But closer
Grammatical errors, graphical
errors, other sources of
unclarity obscure the meaning
of the work. Method of
presentation not well suited to
the problem at hand. Cover
sheet omitted or done poorly.
Novelty &
Creativity (10
%
)
Problem is substantially different
from examples presented in
class, elsewhere in the
curriculum, the book, and other
common resources. While using
reasoning grounded in literature
and prior example, it is not a
duplication or slightly altered
duplication.
To SP
To MAP
Problem is essentially an
existing example with
superfi cial changes, such as a
different temperature or
pressure. There is little
originality inherent in the
problem.
Extraordinary
(optional, up to
an additional 10
points)
Sliding scale of extra points for
being impressive - special
technical prowess, creativity, or
communication; something that
goes beyond.

Appendix C: Example (ish)
Name:
Margot Vigeant
Item:
A short video showing the flammability of a particular water/ethanol mixture at two temperatures with a
reflection on the results; three sets of calculations of the flashpoint temperature for that mixture using
ideal solution (Excel), modifi ed Raoult’s law with Margules equation (Excel), and using UNIQAC in Hysys.
Imagine this goes with a 2 minute video in which I (with fi re extinguisher available) warm up an ethanol
mixture and set it on fi re for dessert, then supported by several calculations as described above. At the end
of the video, I would have an additional segment sharing the calculation results and reflecting on which of
the three approaches was the best way to model reality and why that does (or does not) make sense given
what we know about that model.
Main High Level Outcome:
#2 - VLE and property modeling
Additional Specifi c Outcomes:
Be able to predict the properties (for example, generate a Txy or other equilibrium diagram) of a mixture,
know the limitations of that calculation, and be able to use such calculations in the design of separation
equipment and other unit operations.
Be able to apply any of the above, alone or in combination, to a complex, real-world problem, and
integrate its analysis with information from other courses and outside research in order to design
something that is technically and socially appropriate.
Be able to demonstrate comprehension of complex thermodynamic concepts by explaining them in terms
that someone with less training can understand.
Be aware of computational and properties resources that help with the above calculations, where to fi nd
them, what their limits are, and how to use them.
Continue your practice of teamwork, oral & written communication, open-ended problem solving skills,
and work on development of professional skills, including job search and interview skills.
Reflection:
In working through this problem, I was surprised to see again how different the concentrations we’re used
to working with in every day life, such as v/v%, are from mole fraction. Something with a substantial
concentration in “real life” units will still be mostly water when considered through mole fraction. I was
also surprised at how well the Margules equation performed relative to the UNIQAC model. This is likely
because, as an empirical model, the Margules parameters I used describe precisely these conditions with
high accuracy, whereas the UNIQAC solution works under a wider variety of conditions. I also learned that
it’s very important to have longer matches!
