Notes used during the class
The spreadsheet with the Ergun equation example. Use it to try
- different lengths of reactor
- different catalyst particle sizes
- different pipe diameters
- gas properties (e.g. density)

to see the effect on pressure drop in the packed bed.

Audio and video recording of the class
Codes to solve the example in class are available on the page software for integrating ODEs.
