If I treat you as though you are what you are capable of becoming, I help you become that.

2: GradingThe grading in ENGR 435 will reflect what is observed of your understanding of process systems operation. Evidence of this understanding can be observed in your
• ability to apply the principles to a physical system (performance in the laboratory and quality of results)
• ability to interpret, describe and explain experimental and modeling work (reports and presentations)
The weights given will be
40 points Physical laboratory
(attendance, performance)
30 points Reports
30 points Presentations
Lab work will be graded on this scale
points for Leadership Contributions
Participation Creativity
Cooperation Teamwork
0 points Absent
The semester grade will be determined by your point total
90-up A
80-89 B
70-79 C
65-69 D
0-64 F
The following must be completed to receive a passing grade in the lab:
2 reports, 3 presentations, performance descriptions and a submitted report notebook.

3: Objectives & Guidelines Page XXX
3: Objectives & GuidelinesObjectives
The main objectives of the laboratory experiences are to help you sharpen your skill in observing what happens to an engineering system and to accurately and completely describe what you observe.
Guidelines on Safety, Cleanliness, Conservation, Citizenship
We have had over three years of experience with no lost-time injuries in this lab. Let's all do our part to make this year another one. In the event that someone is injured in the lab and is bleeding, before you help them, put on latex gloves that are available in the lab. Have someone show you where they are.
These labs are not routinely cleaned by the custodial workers. We have to keep them clean ourselves. Always leave the lab cleaner when you leave than when you arrived. If the trash cans are full, set them in the hall to be emptied. If an empty trash can is outside the door, bring it into the lab.
Around computer workstations, do not have food or drink. If you have food or drink elsewhere, please clean up your stuff. Recycle aluminum cans and Styrofoam containers. Rinse them first if there's grunge in them.
Conserve resources and money by printing only what is necessary for effective learning. If you print something that you don't need, place the paper in the "one-side-good" recycle stack to be reused. (Put the good side up.) If you are printing a draft, please use paper from the "one-side-good" stack.
Printers are not instantaneous. This lab has one printer and many users. During heavy use times, plan twice and print once. This will reduce frustrations. In the event you don't get a printout instantly, re-read this paragraph.
If you have any suggestions to improve this lab, pass it on to an instructor or assistant.

5. Assignments Page XXX
5: AssignmentsWeek 1 Introduction
Describe how to determine the fuel usage (miles per gallon) of your car or truck.
Here are some data for gasoline purchaes. Calculate the miles per gallon for these. List the things that might need to be considered in describing why the results are not all the same.
Each Week Work Statement
Each week that the lab meets, you are to submit a weekly Statement by noon on Friday. If you submit the statement on paper, you are to submit two copies of the statement; one each to Dr. Cunningham and to Dr, Henry. You may submit the statement electronically from the 435 Web Site (http://chem.engr.utc.edu/435) and no need to duplicate it.
List the Project you were assigned and the Objective that you plan to accomplish in your project. Describe what you view as the first task to accomplish on your project. Describe what method of approach you plan to use. Also describe any resources that you will require to accomplish you goals.
The Work Statement is to describe your activities in the lab and following the lab. It is to include the data you collected. The data must be presented clearly so that another engineer can understand it. It is to include any calculations and/or graphs that you have completed. Again, these must be presented clearly.

what your activities were in the various weeks
what contributions you made in the laboratory
(background work, operating help,
reporting or presentation)
how you displayed leadership
how you exhibited creativity
when, where and how you were cooperative and worked as a member of a team
Make the last paragraph a summary of the earlier parts of the memo.
Your memo should deal almost exclusively with specifics. In the last paragraph, and only in the last paragraph, you may make general statements about your part in ENGR 435.
Here are suggested first sentences:
This memo is in response to your request. In here is a description and documentation of my part in ENGR 435 so far this semester. For each project I was involved with, I describe my participation, leadership, contributions, creativity and team work.

Appendix A2 STATISTICS
Variations in Measured Quantities
(ENGR 322)
Every time an experimental measurement is taken, there is some error associated with the measurement. Today you are to determine the error in measurements in your system. Do this by taking steady-state measurements of the output function, C(t), for a number of data points. Find the mean and standard deviation of the measurements you make. Report your results as mean±2x(standard deviation). This range will include the true value of the function at a confidence level of 95%. Be aware that the standard deviation may be different at different operating points. Software packages like Excel or Kaleidagraph can help a lot with the statistics.
