Transport Phenomena III - Mass Transfer
Chemical Engineering 522, Winter 2001
Course Description
The objective of this course is to explore in detail the mechanisms of
mass transport in gas, liquid, and solid phases. These include fundamental
aspects of diffusion in binary and multicomponent solutions, correlations
for convective mass transport, and phase equilibrium for interphase mass
transport. It is my intention to introduce open ended problems that require
educated guesses and estimates on your part. You also should be aware that
the textbook will not always have all of the necessary information to complete
a given problem. You will need to become familiar with other sources of
physical property data. On succesful completion of this course, you will
be able to:
-
Set up the differential equations describing a mass transfer process in
a simple geometry, make judicious simplifying assumptions and solve the
remaining equations.
-
Identify and apply the proper empirical correlations for mass transfer
in complex geometries and/or convective flows.
-
Understand and apply the concept of equilibrium stages for simple separation
processes.
Course Policies
Homework assignments will be due at the beginning of class on the due date
given on the class schedule (usually Wednesday mornings). No credit will
be given to late homework. Late homework must still be completed
and submitted within one week of the due date to receive a score of zero.
A score of -10 will be given for each assignment not submitted before the
one-week deadline.
The problems in this course are long and complex. You are encouraged
to work together on homework but simple copying of solutions is unacceptable.
Presenting someone else's work as your own is plagiarism. You are expected
to be familiar with the university's policies regarding academic misconduct.
I will initiate proceedings in all cases where I suspect any impropriety.
Attendance is required and absences will adversely affect your grade.
If
you must miss a lecture for any reason please contact me with an explanation
(292-2256) BEFOREHAND! I will be much more flexible in scheduling make-up
work if you contact me prior to missing a deadline.
There will be two exams of one hour and fifty minutes duration which
will be held during the Thursday recitation sessions. Quizzes will typically
consist of one or two problems to be completed in 40 - 50 minutes and will
be given during recitation periods. A comprehensive final exam will be
given on March 12 and will also be one hour and fifty minutes in length.
Exams (including the final) and quizzes will generally be closed book and
closed notes unless otherwise specified (A 1 page - 8.5 x 11 inch sheet
of paper with any notes will be allowed for exams).
Regrades
Although extremely rare, the instructor or the TA have been known to occasionally
make mistakes when grading. If you believe a mistake was made and that
you deserve more points on a homework or exam, write a short note of
explanation and resubmit your work to Dr. Koelling. You must do this
within one week after the assignment in question is returned. Assignments
resubmitted after one week will not be considered for correction. Exams
are randomly and routinely photocopied and if you are caught changing answers
and then submitting for a regrade, you will be charged with academic misconduct.
Format for Homework, Quizzes, and Exams
By now you should be familiar with how to properly present your work. Please
write only on one side of the paper! Your work must be legible and
easy to follow: be sure to define your variables, state all assumptions,
cite sources of data, and clearly indicate your final answer. Assignments
should be labelled with your name, mailbox no., assignment no., and date.
Multiple pages must be stapled - failure to do so will result in part of
your assignment being lost.
After solving a problem, always take a second look at your answer and
ask yourself whether or not it seems reasonable. If not, don't attempt
to "fudge" your calculation, but write a brief comment indicating that
you suspect your answer is incorrect. For example, if you end up with a
negative absolute pressure, we will be more lenient grading your work if
you tell us you know this is impossible.
