Textbook and Course Notes

  • Datta, A.K. 2017. Heat and Mass Transfer: A Biological Context. CRC Press. I follow the textbook very closely. The textbook has additional explanations and, most importantly, problem solving strategies throughout. Homework problems are assigned by number from the text.
  • Datta, A.K. 2018. BEE 3500 course notes. Copies of all overheads used in lectures are provided to you at cost.
  • Both available at Campus Store. Prior year versions should not be used.
