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)

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

Nomenclature List all symbols/ variables used throughout the report (including in sample calculations) List in alphabetical order Keep greek symbols in a separate list VariableDescriptionUnits ACross sectional area of columnm2m2 UoUo Air superficial velocitym/s

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

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

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

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

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

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

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

References List references in order of use in the report For example Wiens and Pugsley [1] found the bubbling frequency to increase with the gas superficial velocity.
