Period I Reports

Terry A. Ring

Equations

• Complete– Middle of Sentance

• Comma after

– Ending Sentance• Ending punctuation (period)

– Balanced Stiochoimetry on Reactions

• Units of Constants

Engineering Terms

• Please use them instead of slang– Examples

• Theoretical mole concentration => equilibrium mole fraction• Theoretical empirical model=>???• Horizontal radial system=>???• Electronic microscope => Electron Microscope

– digital microscope

• Liquid level efficiency=>Murphree liquid efficiency• Fowling Factor => Fouling Factor• Step limiting heat transfer=>??

• In a company, your reports are archived and used by others,

• don't show a lack of professionalism

Writing

• Clear

• Concise

• Coherent

• Parallel Sentence Construction

…. creating a vapor that is enriched in the more volatile components and a liquid that is enriched I the heavier components.

less volatile

Intro

– Give some explanation of why the experiment or the equipment has value for chemical engineer

– State the problem (or reason for this experiment) in your own words

– Finish with your approach to resolving the experimental problem.

– This should be 1 page or so in length

Theory

• Should cover all ideas/concepts/theory used in results and discussion section.

• All equations need to have text describing them.• Figures/Tables are allowed in Theory section.• Need to reference things more thoroughly

– Each major idea– Each equation

References

• Use more thoroughly– Research your topic more thoroughly

Error

• Error is the single most important thing in Lab work – get error as low as possible in your work!– Clearly state your errors in all numbers (theory calc.

or expt. result), tables and figures.

• Error analysis on all values presented is critical for quality work!

• Comparison of your work to theory and others is critical to quality work

Conversion at 3 residence times of sodium hydroxide vs. stirrer rpm for 1.3 L baffled stirred tank reactor operating at a flow of 1.265±0.03 ml/s for 0.134 ±0.006 M NaOH (the limiting reactant) and 1.019 ±0.02 ml/s 0.167 ±0.009 ethyl acetate. This reaction is second order overall.

Tables & Figures

• Figure Stands Alone/Table Stands Alone– Legend needs operating conditions and more

about how to interpret the figure/table

• Compare to theory whenever possible

• Other– Units of Figures and Table column heads– Do not forget axes titles with units

Results and Discussion

• What is required for Results and Discussion?

– Here are the results, you (the reader) figure it out. (C)

– Here are the results and here is what they mean. (A)

Results & Discussion

• Describe Figure• Describe Table

– Tell the reader what he/she is to get from the figure or table.

– The tell the reader what it means– Compare with theory whenever possible

• Tables• Figures• With other data

Nomenclature Section

• Check that all symbols are listed

• Need definition and units for each symbol

Conclusions

• Do not focus on problems with the lab

• Focus instead on the results and error estimates and use of data for comparison to theory or for design purposes

• Be quantitative about the comparison

• Give the results of the design

Last Checks

• Proof read your report– Do not use I or we in the report

• Double check that the equations, Figures and Tables printed correctly

• Double check appendix is complete
