Announcements

  • Assignment 3 is posted. Due 9 October; the solutions will be posted the same day to allow you time to study for the midterm later that week.
    • Clarification in question 1: please ignore the word "needle"; it is simply a rectangular object.
  • There will be a pop-quiz at the start of the class on Friday that will count as question 1 of assignment 4. It must be handed in at class, and it will be similar to this one:
A membrane operating with pure feed of water produced a flux of 0.20 \(\text{kg.s}^{-1}\text{.m}^{-2}\); this was with a pressure difference of 20kPa. When operated with a protein-water mixture and a 20 kPa pressure difference, a flux of 0.04 \(\text{kg.s}^{-1}\text{.m}^{-2}\) was measured at steady state. What would be the expected flux for this same protein-water mixture, but at a pressure difference of 30kPa?
