Getting Help:
Every effort will be made to help you master the course material. Realize,
however, that if you come to see us outside of office hours or without a
special appointment, we may be committed to some other activity. Please respect
the fact that if our office doors are closed or if we are meeting with another
student or professor, we are not available for help. Also note that we don't
provide assistance with homework problems, etc. on the telephone.
Grades:
Approximate percentage grade distribution will be as follows:
Two midterm examinations 500
Homework 100
Short Quizzes, Class Participation
100
Final Exam300
Course Objectives:
For chemical engineers, DC209 is the first course in a three-course sequence
dealing with energy and mass balances. The DCGN209 focuses on the basic laws
of thermodynamics and material properties. The general objectives of DCGN209
are to master the fundamental concepts of thermodynamics and to be able to
apply those concepts to engineering problems. The course is
fundamental to mastery of any engineering discipline, particularly because
the applications of the principles learned are integral to follow-on or parallel
courses. For example, in Chemical
Engineering, principles of phase equilibria form the basis for mass transfer,
and the principles of reaction equilibria form the basis for kinetics.
In order to successfully complete DCGN209, the student should be able to
do the following:
1. Define a thermodynamic system and its surroundings, intensive and extensive
variables, reversible and irreversible process, heat, work, state and path
functions.
2. Solve First Law problems for both open and closed systems, including those
which undergo transient processes.
3. Be able to state in your own words the meaning of entropy and the Second
Law. Calculate the change in entropy of a system and its surroundings as it
progresses from one state to another.
4. Calculate heat effects for sensible heats, heats of reaction, formation,
and combustion for any common chemical.
5. For pure fluids, be able to use tabular thermodynamic data to solve first
and second law problems, apply simple equations-of-state such as the ideal
gas law and the virial equation.
6. For a two-phase mixture, be able to use Raoult's law to calculate the
equilibrium distribution of a component between the two phases at low pressures.
7. Perform simple thermochemical calculations including applications of the
Third Law of thermodynamics.
Description of Homework, Quizzes, etc.
Homework:
“One must learn by doing the thing; for though you think you know it, you
have no certainty until you try"
Sophocles.
Homework is required and will be a part ( 10% ) of your overall grade for
the course. An
assignment will be made every Friday and will be due at the beginning of
class one week later. Late homework will not be accepted under any circumstances.
Solutions to the homework problems will be posted on the class web site before
the due date.
Each numerical homework problem solution must consist of the following clearly
identified components:
1. Known: State clearly the knowns of the problem (e.g., T = 98°C,
V= 20 cm3, etc.). This is where you distill the written problem down to its
essential definition. A sketch is required with this component.
2. Find: State the objective of the problem (e.g., How much work is
required to carry out the stated process.)
3. Assume: State what is not specified and must be assumed (e.g.,
assume the heat capacity is not a function of temperature, the ideal gas
law applies).
4. Analysis: The worked out solution to the problem. State the basis
where applicable and show all work clearly.
5. Conclusion: The result (answer) and any other observations.
Start each problem on a new page and only write on one side of the paper.
Staple the pages of your homework solutions together. Do not submit them
attached with a paperclip or "dog-eared" corners.
Concept questions will also be given in each homework assignment. Start your
answers to the concept questions on a new sheet of paper and again, only
write on one side. Your answers to these should be neatly (legibly) written
and you may answer more than one question per page. Separate your answers
to the questions with at least one blank line. Partial credit will be given.
Points will be deducted for extremely sloppy work. Failure to follow these
guidelines will result in your assignment not being graded and you will receive
a zero for that problem set.
Reading Assignments:
The reading assignment from CB for the next week will be made on a timely basis. Occasionally material from the reading, which is not discussed in the lecture, will appear on an exam or short quiz. Handouts will be posted on the web to supplement CB where necessary.
Final Examination:
The final will cover all of the material in the course, including any new
material since the last hour exam.
Re-grade Policy:
If you feel your exam, quiz or project has been unfairly graded, submit a
request for a re-grade to your instructor in writing within one week of the
return of the item in question. The re-grade will be solely based on your
written request. Re-grade requests on the homework should be submitted in
writing to the grader within one week of the return of the homework.
Class Ethics:
Unless otherwise instructed, all class work, that receives a grade, is expected
to be done individually. An exception to this rule is homework. Cheating will
not be tolerated in DCGN209 .and all incidents will handled according to
the guidelines published in the CSM Brunton (CSM Student Handbook). All students
are expected to be familiar with these guidelines-if you aren't, read them
immediately.
