About the Material and Energy Balance Spreadsheets

Brice Carnahan – University of Michigan

Prof. Brice Carnahan at the University of Michigan has assigned a variety of spreadsheeting problems to his students in the first chemical engineering course, Material and Energy Balances. The problems typically involve solution of a class of problems (suitable for solving many related class home problems), although some are more specifically related to a particular situation (e.g., specification of a force-air home-heating furnace and steady-state simulation of a particular methanol-production process).

The student problem assignments (in Word .doc files) and Prof. Carnahan’s (in one case student) solutions (in EXCEL .xls files) are included in the folder Carnahan_Mat_Eng_Bal_Sheets as follows:
