General Information. You will form groups of 3 (one or two groups of 2 may be necessary, depending on total enrollment). You may choose your own partners.

Each team will perform three experiments during the quarter (3 successive lab periods for each experiment). The following assignments rotate so that each team member plays each role once:

• Planner: The first group member plans the experiment (in consultation other members). As planner you present and discuss a writen planning report at the planning conference, and you are responsible for writting a standard operating procedure for the experiment. (60 pts)

• Group leader: The second group member is the group leader. As group leader, you make sure the required data are collected, and you write the major laboratory report. (100 pts)

• Oral presenter: The third group member gives an oral report describing the group's findings. (50 pts)

All group members must be able to answer questions related to the experiment (during lab), and must help with data collection. A written pop-quiz (25 pts) will be given for each experiment sometime during the quarter to assess your understanding of the experiment and safety issues.

Planning Report. The first group member gives a planning report in the week prior to the start of the experiment (exception: for the first experiment, the planning report must be submitted prior to the second lab period. In this case, the instructor/TA will get the group started during the first lab period). The group must schedule a "planning conference" with the TA, at which time the first group member submits the written planning report and the group discusses the experiment. The expectations for this report are as follows:

• Introduction and literature review. This section should provide some background on the general significance of the experiment to be performed, and the factors that should dictate the performance of the equipment. Previous results from the published literature should be presented.

• Theoretical Foundation. Review the relevant theory (include literature citations). Give key equations, and explain how the experimentally measured quantities are related to the important factors that dictate the performance of the equipment.

• Plan. How is the available equipment to be used (a schematic is usually helpful)? What measurements will be made? How will the data be analyzed? Be as specific as possible. For example, specify ranges over which variables will be adjusted, number of measurements at each condition, etc. Justify these decisions. Also discuss/show expected trends (e.g., qualitative trend plots).

• Appendix on SAFETY. Identify specific safety issues for this experiment. Discuss safe operating procedures for the equipment. Demonstrate knowledge of hazards of all chemicals used in the experiment.

Limit the planning report to a maximum of 5 double-spaced pages (not including figures, tables, or equations). In the planning conference, highlight the important areas of the report. You need not prepare visual aids, but can refer to figures, equations, etc., in the report. The TA will give you verbal feedback -- suggestions for improving the experiment.

Standard Operating Procedure. One week following the completion of the experiment, the first group member submits a Standard Operating Procedure for the experiment. In industry, a process engineer will often be required to write a document called a Standard Operating Procedure (SOP). A SOP details the step-by-stap tasks that an operator (i.e., someone with little technical knowledge) needs to perform in order to run a process. Thus, a well-written SOP is a recipe that anyone can follow to perform the experiment. A typical SOP has the following format (please follow this format).

0. Emergency Shutdown Procedures

0.1 Describes first step in Shutdown

0.2 Describe second step in shutdown

.

.

.

1. Safety

1.1 Physical Hazards

(Electrical, mechanical, temperature, etc.)

1.2 Chemical Hazards/Handling Procedures

1.3 Other Hazards

1.4 Precautions and Protective Gear Required

2. Description of System

2.1 System Overview

2.2 Manipulated Variables

(Describe all of the controls you can use to manipulate the behavior of the

system, such as valves, power to the pumps, etc. Also include any part of

the system that is selected by the experimenter, such as diameter of a

sphere, size of an orifice plate, etc.)

2.3 Measured Quantities

(Describe all of the measurements you can make, and the tools you use to

make them.)

3. Operating Procedure

3.1 Describe first step

3.2 Describe second step

.

3.? Replicate measurements

(List which steps are repeated for replicate measurements)

4. System Shutdown

TheVacuum Operations :System Operations Manual by Prof. E.M. Stuve (used in ChE 436) is an example of a thorough and easy to read SOP.

Major Report. One week following the completion of the experiment, the group leader must submit a major written report. This report should focus on the data collected and its interpretation. Include the planning report as an appendix. Thus, the main body of the final report should not repeat information contained in the planning report, but should refer to the planning report when appropriate. Data sheets, complete sample calculations, and other details should also be included as appendices. The main body should include the following:

• Summary of findings. Include tabular results and/or figures as appropriate. Give estimated accuracy and precision (and explain basis for estimates).

• Discussion. How do the results compare with the work of others, with expected trends, etc. Explain any deviations from expected behavior. Generalize your results, if possible.

• Conclusions and recommendations. (Don’t just repeat the summary section).

Limit the report to a maximum of 10 double-spaced pages, not including figures, tables, and appendices. Be as concise and specific as possible. Wordy reports will be penalized. You may consult your own group members, but may not consult other students or lab reports from previous years.

Oral report. The speaker should summarize the group findings. Thus, the speaker must consult with the other group members and should participate in the analysis of data, etc. The talk will be limited to 7 minutes. The speaker should focus on the interesting aspects of the findings. Discussion of theoretical background should be minimized (but included where necessary for clarity). The use of visual aids (transparencies prepared in advance) is strongly encouraged. The report will be graded with comments.

Lab Performance. All group members are expected to be in the lab at the beginning of class, and to participate in the collection/analysis of data. The instructor/TA will deduct points for the following:

• Safety violations (e.g., not wearing safety goggles at all times; eating/drinking in lab; improper handling/disposal of chemicals).

• Inability to explain the purpose of the experiment, methods being used, etc.

• Tardiness or unexcused absence.

• Poor housekeeping (flooding the lab with water, area not cleaned up at end of day, etc.)

Data sheets. All data must be recorded in ink on data sheets that are given to the TA at the end of the lab period.
