  15. Laboratory procedure Pre-lab Lab notebook Lab notebook preparation completion 2 weeks Lab day Report due

  16. Pre-lab Expectations

  17. Lab Performance • 10% of final mark (4 x 2.5%) • Be prepared for • Objectives • Theory • Parameters to be measured • Apparatus and procedure • Initiate the contact for pre-lab help

  18. Lab notebook • Title of lab performed, date performed, names of group members. • Objective • Apparatus (labeled) • Procedure • Data • Sample Calculations • Only required when writing a tech memo • Must be hand written Pre lab

  19. Lab notebook • All entries must be hand written • Apparatus may be photographed and pasted in the book if appropriate • Computer data may be printed and pasted • Must be signed and dated by laboratory demonstrator before leaving lab • Record all data and observations • Due April 9th, 2007 • 10% of final laboratory mark

  20. Writing reports and memos

  21. Reports • Each student will write 1 formal report, 1 brief report, and 2 technical memos

  22. Notes on writing • When preparing reports, consult the writing guide on the course website (will be available Jan 11) • All figures and writing should be done on a computer • Figures are placed within the text in formal and brief reports, but after the text as an enclosure for technical memos

  24. Table 3: Summary of statistical analysis

  25. Formal Report • Title Page • Abstract • Table of contents • Nomenclature • Introduction • Theory • Apparatus • Procedure • Results and Discussion • Conclusion • Recommendations • References • Appendices

  26. ChE 333 Chemical Engineering Laboratory I Brief Report Title of Experiment (use bold-faced character) Conducted by: Your name Lab Partner: Name of your lab partner Date Performed: Month Day, Year Date Due: Month Day, Year Department of Chemical Engineering University of Saskatchewan Date received: (office use only)

  27. Abstract • State the objective of the study • Briefly describe how the results are obtained • State the important results in a concise and quantitative form • No tables, graphs, or figures • Summarize the important conclusions • Normally no more than 250 words

  28. Nomenclature • List all symbols/ variables used throughout the report (including in sample calculations) • List in alphabetical order • Keep greek symbols in a separate list

  29. Introduction • State background information that aids in understanding of the experiment/ subject • State the relevance of the experiment to industrial processes • Clearly state the objective of the lab • Cite any references

  30. Theory • Provide a theoretical background necessary for completing calculations & understanding the experiment • State and justify any simplifying assumptions • Describe how model parameters are obtained • Cite references

  31. Apparatus • Provide a computer drawn process flow diagram of the experimental apparatus • Use proper engineering conventions • Describe the apparatus, including important dimensions • Model/ size of measurement devices

  32. Procedure • Outline the experimental procedure • State range of input variables used in experiments • Clearly state operating constants

  33. Results and Discussion • Most important section of the report • Results should be explained in text and presented in graphical form • Trends in data should be justified with physical arguments • Experimental results should be compared to theory whenever possible • Calculate a % error • If discrepancies exist, why? • Read pages 5 & 6 of Writing style and standards in undergraduate reports

  34. Conclusion • ‘Answers’ the purpose of the experiment • No new information should be presented in the conclusion; important information from the results and discussion is summarized

  35. Recommendations • Make recommendations on how we can improve the laboratory • Different measurement techniques or procedures? • Use different equipment?

  36. References • List references in order of use in the report For example Wiens and Pugsley [1] foundthe bubbling frequency to increase with the gas superficial velocity. Similar findings were observed by Kunii and Levenspiel [2]. [1] J. Wiens, T. Pugsley, Tomographic imaging of a conical fluidized bed of dry pharmaceutical granule, Powder Technology 169 (2006) 49 – 59 [2] D. Kunii, O. Levenspiel, Fluidization engineering 2nd edition, New York, 1991 105 - 106 Year of publication Year of publication Publisher Volume # Page range info is found Pages Journal Textbook

  37. Appendices • Raw & Calculated data in tables • Sample Calculations For example 1. Calculation of the volumetric flow rate of air through the absorption column Descriptive title Equation used Keep units Result with proper sig figs

  38. Mark Distribution for Formal Report

  39. Brief report • Title page • Summary • Results and discussion • Conclusions • Recommendations • Appendices All sections are the same as in a formal report except the absence of the abstract, introduction, theory, apparatus and procedure sections.

  40. Brief report - summary • Contains: • A brief introduction stating the nature and purpose of the investigation • A brief explanation of the apparatus and procedure • A summary of the important results

  41. Mark Distribution for Brief Report Report Mark = (Total Mark) / 6.2 = _____________ % * GRADE POINT (G.P.) DESCRIPTOR *

  42. Technical Memos • Use proper memo heading (To, From, Date, Subject) • Include Title page • Concise summary of • Introduction • Apparatus • Procedure • Results & Discussion • Conclusions • Recommendations

  43. Technical Memos • Do not state equation used • Should be signed by the author at the end of the text • Graphs can be included • Must be referred to in the text • Include as an enclosure, on a separate page, after the text • Maximum of two pages double spaced

  44. Mark Distribution for Technical Memos

  45. Summary • Labs start January 11 (next week) • Materials required: • Text book • Lab manual • Safety glasses • Before lab day: • Consult Dale for pre-lab (Room 1D25) • Read and understand experimental procedure in lab manual • Experiment title, objectives, procedure, and apparatus in log book before experiment • Reports and memos are due 2 weeks after experiment
