• 13 Oct: one hint and one piece of information for assignment 3, question 4:
  • the "resistances" refer to \(R_\text{m}\) and \(R_\text{c}\) respectively; and note that \(R_\text{c}\) is a time-varying resistance
  • the missing piece of information is that there are 5 plates in the plate-and-frame press; please use this value if you haven't already assumed another.
• 10 Oct: we a guest lecture on Wednesday next week, 15 October. A former 4M3 student that graduated in 2012 and now working at GE Water will be here to talk about membranes; including making a membrane in the class. Hope to see you all here.

• 04 Oct: The next assignment is posted and is due 10 days from now: 14 October. No late hand-ins and MSAFs for this one please. Solutions will be posted right at the due time.
• 03 Oct: the McMaster Water Week is approaching next week, and so are the course projects for 4M3. At least one of the 4 projects will be related to water treatment, and I recommend you all attend the poster presentations on Wednesday, 08 Oct, from 2:30 to 4:30pm, in the MSUC atrium.

If you would like to earn 10% bonus credit for your project, you should attend the poster presentation and interview at least one of the 60 poster presenters. Ask him/her what aspect of water treatment, pollution, or monitoring they are researching; how their work impacts society, and which technological tools they are using. Add this as an extra half-page to your project report.

• 02 Oct: New slides have just been posted for the section on Cyclones. Please print and bring them to class on Friday.
• 24 Sep: the depth of the vessel is likely not required for question 1 in the second assignment. If required, make a reasonable assumption to work with. Once you do so however, redo your calculation with a different depth and see if your answers changed. This way you can confirm the requirement for that assumption.
• 23 Sep: as pointed out on this page laptops will be useful in Wednesday's class. Lots of messy calculations.
• 23 Sep: some new slides are posted for later this week. Please download and bring them to class.
