Standard Format for Chemical Engineering Problems
An engineer's work should be neat, well organized, and easy to follow. You are expected to
follow this standard format for completing chemical engineering problems. Points may be
deducted for work that does not adhere to this format.
1. Use 8.5x11 paper for engineering problems.
2. The problem statement is needed before the solution; a drawing is usually required.
3. No credit will be given for final answers that do not show work involved.
4. Draw a box around your answers. Be sure to include units.
5. The top of each page should contain the following information from left to right:
Course & Section # | Assignment # | Your last name, 1st name | Page #/Total pages
6. Staple all pages of an assignment together in the upper left corner.
COURSE DESCRIPTIONS: Mass transfer and its application to the unit operations of chemical
engineering, including topics in molecular diffusion, convective diffusion, and process design of
distillation and absorption towers.
Course Objectives
After completing this course the student will be able to …
1. Explain the difference between Molecular & Convective Mass Transfer
2. Estimate Gas, Liquid, Pore, Solid Mass Diffusivities
3. Identifying proper differential equations for mass transfer
4. Model One Dimensional MassTransfer Independent of Chemical Reaction
5. Use Experimental systems & models to measure diffusion coefficients
6. Model 1 dimensional systems associated with chemical reaction
7. Explain the Lewis & Whitman Two Film Theory
8. Perform staged calculations for binary distillation and single component absorption
9. Apply Mass Transfer Principles to Biological Systems

It is your responsibility to participate in your learning. Learning is not a spectator sport. It will
take time (minimum of 9 hours per week for this course), effort, work, and involvement. You
should study on a regular basis and not cram for tests, participate in class by being actively
involved in dialogue with your classmates and instructor, think about what you are learning, and
apply what you have learned to solve other related problems. Arriving late, leaving early,
chatting with your neighbors, doing your other homework, or having beepers and cellular
phones turned on during class time are behaviors unacceptable in this class. These
behaviors are extremely disrespectful to your fellow students and your professor. It is ultimately
you who is responsible for you success in this class, not the instructor, not your fellow students.
Take that responsibility seriously.
To facilitate and reward attendance and participation, we will use an electronic student response
system from i>Clicker. You should already have purchased this at the bookstore, and registered
your “clicker” at the i>Clicker website (www.iclicker.com/register). We will be using the
clickers from the very first class, and you will only get participation credit if you have the
clicker. Using the “clickers”, conceptual questions will be asked periodically (in class) to
assess your understanding of course concepts both after lecture and after doing in-class activities.
These questions will take place in two steps. First each person will answer individually. Then
you will form small groups of 3-4 students to discuss your answers. Then you will answer again.
For both attempts you will be given credit simply for participating, to promote open interactions
and discussion in your groups.
I consider academic dishonesty, including cheating, plagiarism, and
fabrication, as defined in the University catalog (see also
http://www.dsa.csupomona.edu/judicialaffairs/academicintegrity.asp), to be a
serious offense and the maximum punishments allowed will be pursued in all
scenarios. This includes completing any homework assignments or using
clicker for another student. If nearly (or totally) identical works are
submitted by more than one student, all parties involved may receive the
maximum punishment allowed. At the minimum you will receive a F for the
course.
