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

Variable

Description Units

A Cross sectional area of column

m2

Uo Air superficial velocity m/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?

ReferencesList 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. Similar findings were observed by Kunii and Levenspiel [2].
