Course Description:CHE 3211 - Chemical Engineering Laboratory I

The laboratory courses provide students with experience testing engineering science and theory. The course is structured for semi-independent study. There is an abbreviated set of formal lectures at the start of the semester, with a couple more during the semester. Otherwise, you are expected to read and use the required materials in the text and those available elsewhere. You will be assigned a new lab team member for each experiment. You are required to work together to prepare for the experimental design review, complete the laboratory experiments, data analysis, and report writing and presentations.The course includes the following topics:

Introduction to statistical uncertainty analysis and design of experiments.

Experiments illustrating physicochemical properties, fluid mechanics, heat and mass transfer principles.

Technical report writing and presentation.

Standard laboratory and unit operations practice and safety.

Course Objectives/Outcomes:

  • Apply principles of stoichiometry, mass conservation and transport phenomena to analyzing unit operations.Define terms used to describe unit operations. Successful students will be able to communicate with other engineers and equipment manufacturers.Develop engineering problem solving skills. Introduction to issues of safety and ethics in chemical engineering.Application of modern computer software-based design tools, such as Excel, Mathcad.
  • Develop independent and team learning skills.

Program Objectives (ABET):

  • Students will apply knowledge from calculus, differential equations, physics, material and energy balances, thermodynamics, and transport phenomena to solve chemical engineering problems (A). Students will be exposed to topics of safety in chemical engineering (F). Students will learn appropriate terminology for chemical engineering (G).Students will recognize that modern chemical engineering problems exist (I).
  • Students will be required to develop and use their computer skills to effectively solve problems; this will include knowledge of the spreadsheet application, Excel, the general purpose numerical methods program, Mathcad, and the process simulator, HYSYS (K).

Program Outcomes (ABET):

  • Written and oral communication of chemical engineering principles. Set-up chemical engineering problems for solution. Expert, creative problem solving. Using computers and industry standard software for model building and solution.
  • Understanding the issues and ethics of responsible, safe design.

Assignments Policies:

Readings: You are expected to read all of the assigned material. You will also be responsible for learning supplementary material presented in lecture to reinforce the main points of the reading. You are expected to attend all classes and lab periods. Students are expected to read the textbooks and apply the principles of uncertainty analysis and technical communication to their reports and presentations.

Homework: Grades are determined from scores on lab conduct, safe practice, lab note books, technical reports and oral presentations.

Lab Notebook: Each individual student is required to keep a bound laboratory notebook as described in the lab notebook policy. See the instructor for an example. The lab notebook will be graded during each lab experiment. The notebook will be graded for neatness, adherence to standard practice, and completeness. Your lab notebook should include all phases of the experiment from prelab design review to data collection and analysis.

Quizzes: Student groups will be quizzed during an "experimental design review" on their preparation for each experiment before being allowed to begin using the apparatus. This includes understanding theory, equipment operation and safety procedures.

Reports: Each team works together to write a single report of their experimental findings (i.e., one written report per team). The first and fourth experiments require a formal report. The second and third experiments require a memo report. Written reports are due to the instructor before or at the beginning of your section lab session as indicated in the schedule. 25% of the possible points will be deducted for each day your report is late. Follow the required reporting formats. Sample reports are also available for your review. All reports must use 1.5 line spacing. All full and memo reports are bound with a cardstock cover using GBC binding. All graded reports must be returned to the instructor. Each individual student will also present the results of the fourth experiment in an oral presentation to the class. Attendance at all oral presentations for your lab section is required.

Special Out-Of-Class Requirements:

All students are expected to know and use the spreadsheet program, Excel, and the mathematical program, Mathcad, etc., for analysis where appropriate. Computer models are used to move from the "learn-by-doing" approach to the "learn-before-doing" in design. Students will need to know how to use PowerPoint presentation software.

Attendance Requirements:

Students are expected to attend all lectures and computer lab periods. Attendance is mandatory during student technical presentations. You are not required to be in the lab during all lab hours, however, you are strongly urged to use this time for data collection, analysis and report writing. Students are limited to the scheduled laboratory hours for access to the equipment, performing experiments and collecting data. You will have three weeks to complete each lab exercise.

Computer Lab: There will be occasional lectures in the computer lab, Engr 204, to present material to both sections of the lab. These lectures are generally on Tuesdays and Thursdays, at 12:00 noon. It is recommended that you spend time outside of class learning to use various software. You should use appropriate software to solve analysis problems.

Groups: Experiments are conducted by individuals or groups of 2-3 students. You will be assigned a different lab partner for each experiment. The schedule of experiments and groups will be given to you.

Lab Conduct : Safety rules and procedures must be followed at all times.Review the safety policy. Safe conduct includes proper participation with your team in the lab, working equitably and respectfully with your team members, and contributing to the progress of the experiment and reporting. Never leave an experiment running unattended. You may lose points for violations of the lab safety policy or not coming to lab and working with your team, preparing for the prelab design review, running experiments, analyzing data, or writing reports.

The instructors, laboratory services coordinator, and students are all responsible for enforcing safe laboratory practice. Students are required to wear long pants, closed toe shoes, and protective eyewear in the lab. Students will not be allowed to work in the lab without proper safety protection. Repeated violations of safe laboratory practice may result in dismissal from the course.

Tentative Schedule:

Schedule

I. Grading Policy: All grades for academic work are based on the quality of the work submitted, not on hours of effort! The first lab carries 25 points, of which 10% (2.5) is for the preapproval report and in-lab quiz. The next two labs – for which you submit memo reports – carry 20 points each with 10% allotted to preapproval report and in-lab quiz. The preapproval report and in-lab quizzes assesses your preparation for the lab and understanding of lab safety and procedures. There are a total of 35 points for the heat exchanger design experiment. The proposal for this design carries 5 points, the report itself is for 20 points, and your presentation of this report carries 10 points. That presentation grade is the only individual grade you get in this lab; other grades are shared equally with your lab partners.

When we grade your lab report, we look for your ability to figure out and plan what data to gather for a particular project, how well (and safely) you gather them, how you analyze the data and how you communicate those results, analyses and conclusions to us. So, 30% of your report/memo grade depends on your description of the theory, the experiment, the analyses, and the conclusions. Calculations and uncertainty analysis represent 25% of your grade. The clarity, grammar, brevity – in short good technical writing – carries 20%. The other 15% goes for the proper tables and figures in your report. These allocations could vary somewhat depending on the particular experiment – but not too much

Grade / Points / Relative Achievement Level
A / > 94% / Outstanding
A- / 90 - 93%
B+ / 87 - 89% / Significantly above course requirements.
B / 84 - 86%
B- / 80 - 83%
C+ / 77 - 79% / Meets course requirements in every respect.
C / 74 - 76%
C- / 70 - 73%
D+ / 67 - 69% / Worthy of credit although it fails to meet fully the course requirements.
D / 60 - 66%
F / < 60% / Represents Failure. Work was unsatisfactory.

Grades are submitted electronically. Final grades will be made available by the registrar.
