Description

The notebook computes segregation, hold-back, F-diagrams and E-diagrams for different flow situations. These situations include perfect mixing, flow in packed bed with longitudinal mixing, piston-flow in a tube and laminar flow in a tube. For the longitudinal mixing case three expressions [1,2] for the F-functions are considered. We show that these expressions give the same F-Diagram. [1] page 6 in P. V.
