Engineering Faculty
Document No. 49-02
April, 2003 TO: Engineering Faculty FROM: The Faculty of the Agricultural and
Biological Engineering RE: New Undergraduate Course The faculty of the Department of
Agricultural and Biological Engineering has approved the following new
course. This action is now submitted to
the Engineering Faculty with a recommendation for approval. ABE 303
Applications of Physical Chemistry to Biological Processes Sem. 1, Class 3, cr. 3.
Prerequisite:
ABE 210, CHM 257 and Co-requisite: CHE 377 or consent of instructor Physical chemical principles associated
with transport of mass, momentum and energy in bioprocesses. Principles for measuring physical chemical
properties, a description of predictive equations for their evaluation and the
role of these principles in the design and optimization of bioprocesses. Reasons: A
background on physical chemical principles is essential to the understanding of
biological processes. A version of this
course has been offered as an elective course (ABE 591O) for two semesters
attracting the interest of students from Agricultural and Biological
Engineering, Mechanical Engineering and Biomedical Engineering. The number of students in these semesters has
been (18, 15). Sem. 1 01 and Sem. 1 02 ___________________________________________ Vincent F.

semesters attracting the interest of students from Agricultural and Biological
Engineering, Mechanical Engineering and Biomedical Engineering. The number of students in these semesters has

completion of the course will enable the students to: 1. Understand basic principles to measure
and calculate physical chemical properties of biomaterials 2. Identify physical chemical parameters
associated to heat, mass and momentum transfer phenomena occurring in
bioprocesses. 3. Gain knowledge of main factors that
determine numerical values of physical chemical properties associated to
bioprocesses. 4. Use basic principles of rheology to
correlate mechanical properties with quality parameters of biomaterials. 5. Write clear, concise and industrial style
reports. 6. Develop an appreciation for working on a
team to solve a problem related to the measurement or determination of
transport properties associated to bioprocessing engineering Course
