COURSE OBJECTIVES: Develop skills in - Equipment operation - Data recording - Analysis of the data using academic theory - Technical report writing in the selected typical Chem. Eng. processes
Plagiarism is DEFINITELY NOT acceptable! – Copy other people’s report – Citing without referencing the source Plagiarism results in 0 mark for the report Be aware of & Follow the new University of Saskatchewan Academic Honesty/Dishonesty definitions, rules and procedures www.usask.ca/honesty.
Due Date and Overdue Penalty Due date –2 weeks after the experiment date. 7 “free” late hand-in days for the whole course Indicate on your report when use it. Penalty –10% of the full marks (100) per week (1.4%/day) deducted from the late reports –submissions will NOT be accepted after April 7 th, 2012
Requirements Lab performance Write-ups: technical writing Fundamentals of each lab
Lab performance Be prepared for: Objectives Theory / knowledge Design of experiment Parameters to be measured Apparatuses, procedures and principles Find out: what to learn Initiate the contact for the pre-lab help with the lab coordinator
Lab performance Follow experimental procedures Record observations in Lab Notebook Test the validity of data and/or results Pay attention to SAFETY issues – personnel – equipment During the experiments:
Laboratory Safety Safety is the responsibility of everyone and everyone will be held accountable. Safety glasses are mandatory, no exceptions. Contacts should not be worn. Lab coats are mandatory. Absolutely no food or drinks. Several of the experiments involve chemicals which are toxic and hazardous. It is important that YOU know where all the safety apparatus are.
Know where the emergency exits are. Be familiar with the Departmental Safety Manual. Know where the MSDS information is.
Pre - Labs Pre-labs are not mandatory but are strongly recommended. All partners must be present. The laboratory is running two classes this term with an enrollment of 112. Please schedule accordingly as the 3 rd year class will be slow. Pre-lab times are posted on the class website.
Write-ups / Reports Technical memo Brief report Formal report Lab notebook: during the experiments
Write-ups / Reports Evaluate - understanding from the experimental labs. - technical writing skills Technical content: academic theory, results. Writing: organized, neat Language: no grammar or typographic errors Communication: clear delivery
Write-ups / Reports Each student is required to hand in –2 technical letters –1 brief report –1 formal report –1 lab notebook
Write-ups / Reports No repetition in each group for –formal report –brief report –technical letters
Write-ups / Reports YouYour partner Tech. lettersLabs A and BLabs C and D Brief reportLab CLab A Formal reportLab DLab B Lab notebookLabs A,B,C,D In one group, you may label the 4 labs by A, B, C, and D in your own order. Each member of the group should keep the same order.
Lab Notebook No sheets of paper Permanently bounded & recorded Briefly outline the title, apparatus, experimental conditions and procedures before labs Suggest making table for recording data Record clearly all original observations & simple calculations of data MUST be examined, dated and initialed by the TA’s before leaving the laboratory
Refer to the class website for : RULES FOR LABORTORY NOTEBOOKS Submit the lab notebook at the end of the term for marking Lab Notebook
Technical Memorandum Body of text: maximum two pages Introduction - concise introduction of the system used - a brief statement of the objectives of the experiment - a general description of the procedure followed Results - discussions and comparison of all required results with values from literature - a brief table of results can be inserted into text of memo - major graph attached to support the conclusions Conclusions and recommendations Sign your memo on the last page below the text
To: From: (your name, group X) Re: (Lab name) Date: (of the preparation of the memo) Your group logo ( optional ) The text of memo is put here below the line.

Formal Technical Report –Title page –Abstract –Table of contents –Nomenclature –Introduction –Review of theory or literature –Experimental Section: apparatus and procedure –Results and Discussion –Conclusions –Recommendations –Reference –Appendices
Formal Technical Report Title page Course number Name (Your name and state the partner’s name) Lab title Prepared for (instructor’s name) Date lab done Date report due
Formal Technical Report Abstract State briefly the purpose of the investigation Describe briefly how the results are obtained Give all required results in a concise and quantitative format if possible. Use words, no tables, figures and equations Normally no more than 250 words.
Formal Technical Report Nomenclature Completely lists the symbols that appear in your report, their definition and units in a professional and consistent format. Refer to a published paper.
Formal Technical Report Introduction Include information on the subject of the investigation and its importance in industry Cite the references; Describe clearly the objectives of the lab.
Formal Technical Report Literature review or theory Provide sufficient theoretical background to the particular experiments. Develop the equations or models to correlate your experimental data. detailed derivation placed in Appendix Describe how to obtain the model parameters and predict the particular system Cite the references
Formal Technical Report Apparatus and Experimental Procedures Specify the main apparatuses used make, model and use Describe the procedures Highlight important experimental conditions Give the names and quality of the materials. Make sure other people can repeat your work and obtain the same results if they follow your description.
Formal Technical Report Results and Discussions Present the significant experiment results required in the Lab Manual in words and graphs. State the data treatment processes and the outcomes. Discuss the results of experiments and model simulations or predictions. Compare your results with that in literature if available. Logically discuss and lead to conclusions.
Attention Consistent format Conformity of units Figures or Tables in the body of text –Titles of figures, axes, and tables –Briefly state the experimental conditions –Experimental data: represented by unique symbol for each group of data in figures –Modeling curves: different lines with legends –Show model significance when fitting models
Formal Technical Report Conclusions and Recommendations Conclusions should be summarized following the discussions. Lists your suggestions on how we can improve the labs.
Formal Technical Report Reference Completely lists every reference cited, mentioned or used in the text of the report in a professional and consistent format. Follows either the number order or the alphabetical order.
Formal Technical Report Reference format examples In the text: ……Adams concluded that …… 1. However, that conclusion may be suspicious because …… 2 In the Reference section: References 1. Adams, A. B. title of publication. …… 2. Cook, H. M., Author #2, …… Ref: Industrial and Engineering Chemistry Research or in the text: It was concluded ( Adams, 2001) that ……. However, that conclusion may be suspicious (Davis and Volesky, 2001) because ……(Niu, et. al., 2005) References Adams, A. B. year, title of publication, publisher, page (book) Davis, T. and B. Volesky, year, title of paper, volume, issue, pages (paper) Niu, C., M. Huang and M.Volesky, year …. Ref: Canadian Journal of Chemical Engineering
Formal Technical Report Appendices Raw data (neat with tables) Calculated data Sample calculation (using a set of data to show the steps of calculations) Tables and Figures
Brief Technical Report –Title page and Table of contents –Summary a brief introduction stating the nature and purpose of the investigation a brief explanation of the procedures and apparatuses a summary of all the required results –Results and Discussion: include major graphs or tables –Conclusions –Recommendations –Reference –Appendices: only raw experimental data and a sample calculation Absence of abstract, introduction, theory/literature review, materials and methods sections
A good report Consists of: Careful measurements Correct calculations Understanding and use of the theory or models Logical discussions Correct conclusions Organized Clarity No grammar & typographical errors References
