Announcements (previous ones)

  • If you missed class today (18 Oct), please make sure to watch the video recording; Friday's class will not have too much time to recap before moving on. Here are some questions to think about before class:
    • What happens, in terms of osmosis, on a really hot day to fluid flow in a tree?
    • Is \(P_\text{solv}\) going to change if we use a different solute?
    • If we double the pressure drop, will we double the solvent flux?
    • Why did we not take osmotic pressure in account for microfiltration and ultrafiltration?
    • In RO: what will be the expected effect of increasing operating temperature?
  • Important: you should attempt to solve part 1, 2 and 3 of the question posed at the end of class.
