• HOMEWORKS
  • Complete the web-based AU Risk Management Lab Safety Training Course by doing the following
    • From the main AU page, click on "Students", then click on "Blackboard"
    • Click on "Open Blackboard at Auburn University"
    • Click on Course List, then Risk Management, then Risk Management (again), then Uncategorized
    • Click on the triangle by Lab Safety Training and then click on the Register icon at the right side of the screen
    • Register for the course by supplying your AU user i.d. & password. Take the course by viewing the PowerPoint slide show (Lab Safety Training Presentation). When you're done, take the 16 question assessment
    • You will be asked questions about the course material during the 3820 mid-term.
  • View two of the incident report videos available on the CSB site referenced above. Watch the videos in preparation for the mid-term exam.
  • HMWK 0 - GFI report (this assignment was embedded in the Safety Acknowledgement Form)
  • HMWK 1 - problems 2.4, 2.5, 2.9 and 2.10 from the Taylor book
    Be aware that some questions may require knowledge that was not lectured on but was a part of the reading assignment (e.g., Problem 2.4's requirement that the equations be rewritten in their clearest form)
    Due Date: 2 p.m., 6 SEP 11, in lab or in Dr J's mailbox (2nd floor of Ross) or underneath Dr J's office door (Ross 149)
  • HMWK 2 - problems 3.7, 3.18 and 3.24 from the Taylor book
    Due Date: 19 SEP 11
  • HMWK 3 - problems 4.1, 4.10 and 4.16 from the Taylor book
    Due Date: 26 SEP 11
  • HMWK 4 - problem 5.21 from the Taylor book PLUS
    this link should take you to a height chart for white American males. Assuming that the height distribution at a given age is Gaussian, what is the average height of a 25 year old white American male? The standard deviation? Taking these data to be representative of all 25 year old American males, what should the Giraffe Club's minimum height requirement be for these men if they desire the same level of exclusivity as in 5.21a? Comment on the assumption of a Gaussian distribution - do you see any reason to doubt this assumption?
    Due Date: 17 OCT 11
  • HMWK 5 - Teaming Quiz
• READING ASSIGNMENTS (in addition to chapters from Taylor)
  • "Measuring Temperature by Direct Contact" from the September 2011 CEP
• EXPERIMENTS
  • Experiment 1 - Explosive Decompression (aka Mentos & Diet Coke)
  • Experiment 2 - Viscosity
    • Equipment and Objectives - this is available as a pdf file
    • Explanation of Viscosity - about 8 years ago I put together a quick and dirty primer on viscosity for freshmen/sophomores; note that I don't mention Newtonian vs non-Newtonian, etc.
  • Experiment 3 - Piping (aka Friction Loss in Pipes and Fittings)
    • Equipment and Objectives - this is available as a pdf file
  • Experiment 4 - Centrifugal Pump
    • Equipment and Objectives - this is available as a pdf file
  • Experiment 5 - Fluidized Bed
    • Equipment and Objectives - this is available as a pdf file
    • Equipment Manual - this is available as a pdf file. Note that this is the manual from the original equipment manufacturer; some items may have been changed over the years. For example, a blower is no longer used to provide the gas stream through the bed.
    • A nice Fluidization Tutorial by Dr. Martin Rhodes of Monash University (Australia) is available. Be sure to check out his 'Video 1'. Note that is is an archived version of the site as it appeared in July of 2011.
    • And finally, here's an example of possible hysteresis that has nothing to do with a fluidized bed
  • Experiment 6 - Evaporator
    • Equipment and General Objectives - this is available as a pdf file
    • Start-Up/Shutdown Procedures - this is available as a pdf file.
    • Valve List - this is available as a pdf file
    • Evaporator System Schematic - this is available as a jpg file
    • Procedures - Experiment 6B - this is available as a pdf file
  • Experiment 7 - Food Engineering
  • Experiment 9 - Unsteady State Heat Transfer
    • Equipment and Objectives - this is available as a pdf file
