Course Learning Outcomes
Students who successfully complete this course should be able to:
 Sketch a chemical process from a description, or describe a chemical process from a
sketch.
 Identify the parts of a chemical process that involve transformations in composition or
state or transfers of energy.
 Define the terms steady state, accumulation, open system, and closed system, and
differentiate between steady state and equilibrium.
 Convert among mass flow rate, molar flow rate, and volumetric flow rate; and between
mass and mole fraction.
 Write mathematical expressions equivalent to process specifications and physical
constraints.
 Write mathematical expressions based on physical properties, simple equilibrium
relationships and equations of state to describe relationships among process variables.
 Use the Ideal Gas Law appropriately to calculate gas properties.
 Use literature compilations of thermodynamic data to solve energy balance problems.
 Use empirical methods to estimate needed thermodynamic quantities when literature
values are not available.

You must earn at least a C- to continue to the junior CHE courses. There is no predetermined
proportion of A's or F's. Late submissions are penalized 25%. Anyone who does not submit all
assignments will receive an 'F' for the course. You must earn at least 70% of the available Quiz
and Exam points in order to get a C- or better. Subject to those restrictions, grades are computed
as a percentage of total available points earned.

Course Web Sites
Grades are posted on the Blackboard. You can submit your assignments via Blackboard.
Handouts are available at http://cheserver.ent.ohiou.edu/ChE2010/ (password=1234 if any).
Team Projects
Assignment will be distributed via Blackboard. Project will be graded on both technical
communication and technical content. The instructor may individually adjust team grades
considering input from team performance evaluations. Bring personnel problems to the attention
of the instructor early. All team members are expected to participate in resolution of problems.
Uncooperative or unproductive team members can be fired.
Individual Writing Assignments
Assignments will be distributed via Blackboard. This is a JE course. Expect to write, to critique
other peoples’ work and to have yours criticized, and to rewrite. What made your English
teacher happy is not necessarily good technical communication. Technical communication is an
important professional skill for engineers.
Quizzes & Final Exam
Quizzes and the final exam are in class, cumulative, and closed-book. You will be provided with
a copy of “Essential Information for Material and Energy Balances” (available from course web
site http://cheserver.ent.ohiou.edu/ChE2010/). There is no midterm exam for the summer
offering.
Recommended Practice Problems
Recommended practice problems will not be graded; the solution manual will be provided via
Blackboard and is widely available on the web. Chemical engineering is a participation sport.
Most solutions require multiple steps, and you must build the self-confidence to persist when the
solution does not come quickly. At minimum, do the recommended practice problems from
Felder & Rousseau. Some people need lots of practice to “get it,” some need less. Work as many
problems as you need, and ask for help as you need it.
Attendance and Absence
Attendance is not graded. When you attend, we expect you to be fully and constructively
engaged in this class. Whether you attend and how you behave when you do are part of
practicing and building a reputation for professionalism. We will rely on our perception of your
professionalism if we are asked to provide a reference for you.
If you miss a quiz or exam for a legitimate reason, contact Dr. Gu to schedule a makeup.
Arrangements must be made in advance to make up graded work missed for reasons that can be
anticipated. In general, you should complete the graded work prior to the anticipated absence.
Only graded work missed due to illness or death in the immediate family can be made up without
advance notice, and we reserve the right to require evidence as described in the Student
Handbook. In general, we expect you to make up work within 2 working days of your return to
classes. Refer to "Class Attendance" in the Student Handbook for the Ohio University policy on
absences.

Ethical and Professional Behavior
Engineering is a profession; the classroom is a professional environment; ethical behavior is
expected of professionals. Studying engineering means both learning technical content and
practicing to meet professional expectations. The chemical engineering faculty are your mentors
as well as your instructors. We don’t just teach students; we educate engineers.
Any action that deceives your professor or disadvantages your classmates, and any action taken
without due consideration of its possible harmful effect on others, is unethical and will not be
tolerated. Academic dishonesty is defined in the Student Handbook. The typical penalty for
misconduct is zero for the assignment (because the student has not completed it to an acceptable
standard) and referral to the Office of Community Standards and Student Responsibility (because
the student has violated the Code of Conduct). Grades affected by misconduct may be appealed
through the usual grade appeal process. The Office of Community Standards and Student
Responsibility may impose other sanctions, but may not recommend or overturn grade penalties.
