W 11:00am-12:00pm (or by appointment)

Evaluation:
20% Homework, attendance, participation
10% Extended homework project
40% Weekly in-class quizzes (one will be dropped)
30% Final exam (Dec 18, 11:30-2:30, during finals week)

Course Goals/Objectives:

  • Convert among different units and combinations of units in the course of solving a problem.
  • Determine appropriate sources and methods for missing physical property information.
  • Recognize steady state and non-steady state conditions from a verbal description.
  • Perform a material balance on simple or complicated, traditional or non-traditional chemical engineering processes.
  • Perform energy balances on those same chemical engineering processes.
  • Construct and interpret graphs relevant to an engineering problem
  • Interpret engineering diagrams for thermodynamic and other physical properties

    Homework Homework will be assigned each Thursday and will be collected the following Thursday. Late work will receive only partial credit, with the amount of credit being calculated via a decreasing function of tardiness. Students may work in groups to discuss the homework problems, but each student must turn in their own work. Simply changing the name on someone else's spreadsheet or printout doesn't make the work your own. Not all problems will be graded, and the choice of which problems to grade will be partially random.

    Students are expected to turn in every assignment. The course material is cumulative, and trying each homework as it is assigned is a good way to keep up. Turn in your assignment even if it isn't finished. You will receive partial credit and partial feedback.

    The extended homework assignment (i.e. the class project) will be done in groups. Each group is expected to work on the project without input from other groups.

    Attendance Students are expected to attend every class. In-class problem solving will be an important method for learning how to solve the problems. Excessive absences will cause the final grade to be decreased.

    Reading in the textbook is not "assigned" on a day-to-day basis. Instead, each student is expected to read the relevant sections as we go along. The book clearly explains good sample problems, so it's well worth it! The appropriate sections to read will be indicated on the course calendar.

    Disabilities: Any student with a documented disability is welcome to contact me early in the semester so that we may work out reasonable accommodations to support your success in this course. One should also contact Disability Services for Students, Office of Student Life, 330 Memorial Union, 874-2098.

    Academic Enhancement Center: Success in this course requires that you keep up with the class work and study the course materials effectively. The Academic Enhancement Center can help. Their friendly staff of learning specialists and student tutors can help you find an approach to studying that suits your needs and schedule, develop effective study strategies, understand course concepts, and practice productivity. The center is also a great place to go and study on your own, with space available for individuals or groups. They are open Monday through Thursday until 9pm, Fridays until 1pm, and Sundays between 4 and 8pm. The services are free (the coffee is free as well). You can call them for complete information at 874-2367, or just stop by the center on the fourth floor of Roosevelt Hall.

    Computer Facilities: The Department of Chemical Engineering maintains a computer center for ChE students, located in room 207. The Engineering Computer Center (203 Kirk, http://www.egr.uri.edu/ecc/) is open to all engineering majors; ask at the front desk for more details and hours. Wireless access is available in both locations for laptop use.
