COURSE OBJECTIVES

To provide students with an opportunity to reinforce the concepts and theories that they have

learned in their engineering courses. This is achieved by performing systematic experiments

with laboratory equipment to acquire experimental data. The data are then subjected to statistical

analysis to evaluate reliability, followed by interpretation and discussion in terms of known

theories. To conduct the experimental work under conditions that are similar to those existing in

industrial laboratories (e.g., strict adherence to safety guidelines, proper record keeping, being an

effective and responsible team member, promptness in arriving at work, neatness and

industriousness) and thereby to aid in the development of professional work ethics. To use the

experiments as the basis for the presentation of written and oral reports.

Specific outcomes:

1. Ability to describe experimental objectives, theory and procedures; analyze

results with respect to theory and correlation; and formulate conclusions and

recommendations in a clear and concise manner either in written reports or oral

presentations

2. Ability to work with other group members, perform and complete his or her

assigned responsibilities

3. Ability to apply mathematics, basic and engineering sciences to solve problems

associated with the experiments

4. Ability to operate the apparatus, use the analytical instruments and obtain accurate data from the experiments

SAFETY

It is your responsibility to read and to understand the KU safety regulations.

Eye protection must be worn at all times in the laboratory areas. Eating and drinking is not allowed anywhere in the laboratory. Any student entering the lab in open-toed shoes will be

sent home to change and grade penalties will be assessed. Short pants and short skirts are to be

avoided. Care must be taken to keep loose clothing and hair away from machines with moving parts.

If you are in doubt about the safety of a particular experimental step, contact the instructors.

Dr. Snyder will monitor laboratory safety, maintenance, technique, and clean up. Points will

be lost by every member of a group that does not either clean up the laboratory area after an

experiment or adhere to the safety instructions. Accidental breakage may occur in the laboratory

on occasion. However, damage to equipment or property loss due to negligence, failure to follow

instructions, or horseplay is to be strictly avoided and may be grounds for a grade reduction in

egregious cases. Students are expected to maintain a professional attitude while in the

laboratory; after all, most of you will be working as professionals within a year.

3

LABORATORY FORMAT AND SCHEDULE

You will be divided into groups of three/four members. Each group will perform four of the

following six experiments (a Liquid/Liquid Extraction experiment may be worked into the

experimental rotation later in the semester; details will be provided by the instructors):

1. Transient Heat Exchange (HeatEX)

2. Liquid Level Control (Control)

3. Vapor Liquid Equilibrium (VLE)

4. Multistage Distillation (Distillation)

5. Continuous Stirred Tank (CST)

6. Packed Bed Catalytic Reactor (PBR)

The schedule for performing the experiments and submitting the laboratory reports is shown in

the following Table.

All experiments will span three lab periods. This amounts to 24 hours of laboratory time and your

work and reports should reflect this in both breadth and depth. The objective is to give you sufficient

time to do an in-depth study of each experiment. Each group will be asked to review and critique the

work by another group on an experiment that they will perform later in the semester. This exercise is

to allow students more exposure to technical writing and the Report Evaluation while simultaneously

planning a continuation of a previous groups experiment. More details on the critique process and expectations will be provided later.

Reports and Appendices are to be submitted electronically and will be due six days after the final

laboratory period of each experimental session before 12:00pm. Late reports will be deducted 10%

per day of the total points for the lab.

REQUIRED LAB PREPARATION

You must be familiar with the experimental setup and possess a sound knowledge of the theory to

be able to systematically perform the experimental investigations. There will be videos of

instruction for performing the experiments posted on Blackboard. Each group member is expected

to do the following before the end of the last day of the experimental session:

1) View the video of your next experiment 2) Looked over the new experimental apparatus 3) Review the LabVIEW instructions (with the exception of the VLE experiment) 4) Review experiment operation with the previous group. 5) Read the instruction manual for that experiment 6) Demonstrate to Dr. Snyder that you have carried out the above instructions and can fully

operate the apparatus without further assistance.

Groups leaving before Dr. Snyder has recorded this accomplishment should not expect

accurate credit for their preparation.

Prior to beginning laboratory work, all groups will be expected to complete a brief PreLab

assignment distributed and reviewed by Dr. Snyder. The purpose of this assignment is to ensure

that you are prepared to analyze your data at the time it is collected. It should be turned in to Dr.

Snyder by 1:00 pm on the day before the first lab of a new round of experiments. Included in this

submission:

1) Provide the solutions to the assignment 2) List the limits of all operating parameters such as flows, temperatures, pressures,

concentrations, etc.

3) List the defining physical values (e.g. rate constant, conversion, overall heat transfer coefficient, column/stage efficiency, etc.) that the experiment is designed to obtain.

Also by 1:00 pm on the day before the first lab of a new round of experiments you should submit:

1) A list of objectives for your experiment and a plan for meeting those objectives. These should be set based on previous group(s) results and conclusions, if appropriate. This indicates that you are expected to communicate and review earlier groups reports, data and interpretations including other lab sections of this class. You will be expected to explain

how your objectives build on, test, or otherwise increase knowledge about the experimental

system beyond what has been found by previous groups.

2) The operating parameters (temperature, flow rate, concentration, etc.) that you will adjust to allow measurement or calculation of the physical values (see above).

The Instructors and Dr. Snyder can help to refine your plan, if necessary.

Groups will arrange themselves and the division of labor required to plan and execute each

experiment. Laboratory groups are expected to perform experiments from 8:00 a.m. - 3:15 p.m.

Students are not allowed to work in the lab at night or on weekends, without the written permission

of the instructor.

WEEKLY LECTURES

Lecture periods will be spent discussing report writing, data interpretation and examining the

previous weeks data. The instructor will expect to discuss the calculations, experimental plan, and any difficulties encountered by each group.

GRADING

The course grade will be determined based on the following weights:

Group Report 1 (75 pts)

Planning Meeting (10 pts)

Group Critique 1 (15 pts) 100

Group Report 2 (90 pts)

Planning Meeting (10 pts) 100

Individual Report 3 (90 pts)

Planning Meeting (10 pts) 100

Group Report 4 (90 pts)

Planning Meeting (10 pts) 100

Group Oral Report 50

Total = 450

Within the grade for each written report, 10% of the total points will be determined by effective

oral communication of the group members in explaining the apparatus, procedure, experimental plan

and hypothesis. This planning meeting will occur during the first lab period of each experimental

session. Proper preparation in understanding the operation of the experimental equipment and

planning an effective experiment will be necessary for this section of the grading. The questions for

this portion of the report can be found on the course Blackboard page.

Attendance at the laboratory session by all group members is expected. Situations may arise

during the course of the semester where a student may be allowed an excused absence. It is your

responsibility to let the instructor and your group members know before the start of lab that you

will be absent. Failure to notify the instructor and have your absence for any portion of the

lab period approved by your laboratory group before the start of the respective lab session

will result in a 2%/hr deduction for the overall report grade for the individual student. A minimum score of 50% on the individual portion of the grade is required to pass the course.

DISABILITIES:

The KU office of Services for Students with Disabilities (SSD) coordinates accommodations

and services for all students who are eligible. If you have a disability for which you wish to request

accommodations and have not contacted SSD, please do so as soon as possible. Their office is

located in 22 Strong Hall; their phone number is 785-864-2620 (V/TTY). Information about their

services can be found at http://www.ku.edu/~ssdis. Please also contact the professor privately in

regard to your needs in this course.

ACADEMIC MISCONDUCT AND ETHICS:

Ethics are an important aspect in the career of any current or future Engineer. This skill set

begins and overlaps with Academic Ethics. Article II, Section 6 of the Rules and Regulations of

the University Senate describes academic misconduct. The Chemical & Petroleum Engineering

Department has approved a policy document that further explains academic misconduct with

examples and tips for avoiding violations. The official document can be obtained at:

https://cpe.engr.ku.edu/sites/cpe.engr.ku.edu/files/docs/Academi

c%20Misconduct%20Policy%20Guide%20Approved%201_15_15.pdf

PLEASE READ THIS DOCUMENT IN ITS ENTIRETY. For the purposes of this course,

academic misconduct shall include plagiarism while preparing reports, and giving or receiving

unauthorized aid during preparation of "individual" reports. WHENEVER YOU DECIDE TO

ADOPT PORTIONS OF TEXT FROM ANOTHER SOURCE VERBATIM, PLEASE BE

SURE TO INCLUDE QUOTATIONS AND TO PROVIDE PROPER CITATION.

In this course, students may NOT possess other students materials (data analysis, calibrations, reports, etc.) from prior semesters of this course or other current lab groups and sections unless

specifically encouraged by the instructors to collaborate in data collection and share findings

(excluding analysis) with other groups.

In this course, students are required to work and learn together on assignments and laboratory

work (PreLabs, data collection, etc.). However, the following instructions apply:

- Students may work together in groups to create a single group assignment with a single grade. The only exception to this rule is on specifically identified assignments where

students will work on an experimental plan and data collection together but will work

individually on analyzing the data and creating a final report. The group may decide on the

delegation of work, but each student must participate.

Cell Phone Usage: Please refrain from talking or texting on your phones when an instructor is

working with a member of your group or with the group collectively. You are otherwise free to

use your cell phones as you see fit.

LAB NOTEBOOKS

It is essential that you properly document your work in the lab notebook. The primary

purpose of the notebook is to archive your experimental conditions and raw data. One should be

able to look at the lab notebook and see exactly what you did and look directly at the raw data

you obtained. The report you generate is a synthesis of the data and is subject to various errors

of manipulation and interpretation. The notebook contains the original raw data.

Your notebooks will be inspected. They should contain the following:

1. Title of experiment, names of experimenters, date. 2. Room conditions (temperature and pressure) 3. Brief (but complete) description of what you did; in sufficient detail that someone else

could repeat your work.

(Example: 10:00 am ran heat exchanger with countercurrent flow. Hot inside cold outside. Hot inlet temperature was 55 C, cold inlet 18 C. Flow rates varied as reflected in

data table below:)

4. Data As much as is possible, enter data in lab notebook directly. Do not collect data on another sheet or clean it up and transcribe to notebook. In the event your data are taken on LabVIEW, refer specifically in the notebook to the filename and location.

PREPARING REPORTS

Your writing style should be concise and precise using simple sentence structures. Please get to

the point: We want to see what you did, why, what you found out, how you can verify it and

how does it relate to the overall goals of the lab. Grammatical and typographical errors are not

acceptable. Although not a concrete rule, passive voice is generally used in technical writing.

Please prepare a rough draft of your report; and then edit it. While reading, you must examine

carefully if your sentences unambiguously convey what you intended them to convey.

Computers with word processing software are available in the computer laboratories. Type

should be neat and professional, with spacing, font and margin sizes comparable to what you find

in this handout (though double spacing is preferable). A variety of computer tools is available to

assist you in data analysis, preparing graphs, charts and tables. It is expected that you will use these

tools routinely in the analysis of data and the preparation of reports. Your report will be eventually

submitted in electronic format.

(Reports should be formatted as they were in C&PE 616 and a more detailed explanation with

examples can be found on the course BlackBoard page.)

I. Detailed Report

The purpose of the report is to provide a complete exposition of the theory and techniques used

in the experiment and to compare the results obtained with established theories and/or literature

values of measured physical parameters. The report is not to exceed 10 pages including figures

and tables, but excluding appendices. The report format should be as follows:

(i) Title. This should include an appropriate short title (100 characters or less including spaces)

that adequately describes the work done. The author name(s) should appear below the title,

together with the dates of the experiment and the date the report is submitted.

(ii) Abstract. The abstract should appear below the title. The purpose of the abstract is to

summarize the information of the report in 250 words or less. The abstract is self-contained and

requires crisp, explicit, concise sentences to state what experiment you performed and what your

findings were. In other words, results should be stated concisely without references to either

external or internal sources. Writing an abstract requires a great deal of thought and is usually

done after completing other sections of the report.

(iii) Introduction. The introduction serves to explain to the reader the purpose of the work that

was done, the motivation or importance of the study, the way in which it was done, and how the

present work relates to previous studies of the same topic. This is where a literature survey

should be presented. You are expected to go to the library or online to obtain articles relating to

the necessary physical constants, previously measured values of the quantities you are

measuring, and alternate developments of the theoretical portion of the report. Proper

bibliographic citations should be used for all information derived from the literature.

(iv) Theory. The theory section is used to provide the appropriate equations that apply to the

experiment. A precise statement of the assumptions, governing differential equations and

boundary conditions generally helps to define the problem under investigation. Key equations

are to be presented. You should choose the appropriate starting point for the theoretical

8

development. Complex intermediate steps in the derivation of equations are to be avoided in the

main body of the report. Instead, you must concisely state how one line of equation follows from

the others. Equations must be typed in using the appropriate software. Equation numbers must

be flush with the right hand margin. All symbols must be explained (with the appropriate units)

directly following their use and in the Nomenclature section.

(v) Experimental. The experimental section should provide sufficient information to allow

another worker to attempt to reproduce the experimental data being reported. This requires a

clear description of equipment (with a schematic diagram of the apparatus), experimental

conditions, instrument calibration details, measurement uncertainties and experimental

procedures. This section should NOT be presented as an instruction manual but should cover

only the important steps and parameters of the experimental investigation.

(vi) Results and Discussion. (This is considered to be the most important part of the

report.)

This section presents the final results in tables and/or graphs and compares the measured values

with existing data and theories. Well-conceived tables and figures are essential for conveying

information in an easy-to-understand manner. Hence, it is imperative that you give adequate

thought on how best to present your results. Avoid providing results in a multi-page table with

several rows and columns. In such a case, the results should probably be presented on a plot. A

figure title should be descriptive of the phenomenon or trend that the graph is intended to convey

(e.g., "Effect of temperature on product selectivity" rather than merely stating "Plot of x vs. y").

Also, appropriate legends must be included in the figures to provide complete information on

experimental conditions specific to the plotted data. All tables and figures should have a

descriptive title and a number. They must be properly integrated into the text. In general, they

must be placed immediately after the paragraph in which they are first referenced. Labels, scale

and symbols on figures must be legible even after size reduction that may be needed to properly

integrate the figure into the text. If you do not refer to a figure or a table, do not include them in

your report.

In discussing your results, you must carefully lead the reader through your data. You should not

assume that the reader will sort through your figures and tables to find results that substantiate

claims. Rather, you should make statements like, As Fig. 2 shows, if ln x is plotted versus time, linear behavior is observed for times greater than 30 minutes and less than 200 minutes. Finally and most importantly, dont just report the results. Discuss and interpret them based on the theories presented earlier. Discussion of the source and a quantitative estimate of

experimental errors must be included in this section.

(vii) Conclusions and Recommendations. This short section summarizes the most important

conclusions, evaluates the results and proposes future studies. Often, the conclusion section

repeats portions of what is already found in the abstract, but it is a necessary part of any report.

(viii) Nomenclature. All the symbols used in the report must be listed and defined in

alphabetical order and units listed. Roman and Greek letters should be listed separately.

(ix) References. All references to books and articles used in the text are listed here. They can be

listed in two different ways: (a) Numerical citation, by numbering the references in order of their

9

appearance in the text of the report (for example [1]), or (b) Alphabetical citation, by citing the

author and year, and listing the references in alphabetical order in the reference section [for

example: Bird et al. (1960)]. Literature references should be given in only one of the standard

forms, and must be complete. You may wish to learn the software EndNote (free on the KU website) or use the endnote feature of Word.

(x) Appendices. Appendices must be compiled with the same attention and care required for the

main report. Appendices must include supporting materials such as raw data, sample calculation

and error analysis. Since appendix materials are referred to in the text, they are to be organized

as follows:

Appendix A: Uncertainty Analysis

While it is preferred to input equations using Equation Editor, etc. into a Word document, the equations in this section may be hand-written.

This section should progress logically, showing how how you determined the uncertainty of your results.

You must indicate in the report text that details of uncertainty analysis are provided in Appendix A.

Appendix B: Instrument Calibration Details

This appendix supports the experimental procedure section where calibration procedures and measurement accuracies are discussed. This appendix must include calibration plots

for thermocouples, flow meters or pressure transducers. You must indicate in the main

text that these details are provided in Appendix B.

Appendix C: Experimental Data and Computed Results

Provide data and results in tabular form. Tables are usually derived from the spreadsheet used in the computations. In general, spreadsheets may have to be modified to arrive at

legible tables. Be sure to include only essential columns and a justifiable number of

significant digits.

Table must bear a descriptive, yet concise, caption.

Experimental conditions that are common to the data may be stated immediately under the caption (For example, if you are reporting several data at a common flow rate and

temperature include these under the caption).

Column captions must clearly indicate the data or computed results that are presented including the proper units.

Error estimates on computed quantities such as friction factor, heat transfer coefficients etc., must be shown on columns right next to these quantities.

Appendix D: Sample Calculations

While it is preferred to input equations using Equation Editor, etc. into a Word document,

10

the equations in this section may be hand-written.

All equations used in the analysis should be listed in this section and then a sample calculation for each equation should be shown.

Indicate clearly the set of experimental conditions and data for which sample calculations are being performed (e.g., data pertaining to the first row in Table C1 of Appendix C).

Formulas and physical property values (molecular weight, density, viscosity, etc.) used in computing experimental results such as reactant conversion, friction factor, etc, and

errors thereof, must be clearly shown and any literature sources properly cited.

Substitution of units and check for dimensional consistency must be clearly shown so as to enable the instructor to easily verify these calculations.

Appendix E: "Other" relevant information

Summary of how instructors comments from previous report were addressed

Any tables and figures that provide additional supporting data to strengthen your results and discussion but do not fit in the main appendix. This appendix is not to be used

simply as a dumping ground for extraneous material.
