You have already determined the predicted pressure drop for the 95 cm column with spherical 120-um beads and an average void fraction of 0.32 (3.4 MPa). However, when you started to use the column the observed pressure drop was 4.5 MPa. a) Determine a single void fraction that would explain this pressure drop. b) Determine a void fraction and fraction of the column length that would explain this higher observed pressure drop.

TGhe predetermined pressure drop was 2.4mpa if that helps, please help im lost

You have already determined the predicted pressure drop for the 95 cm column with spherical 120-µm beads and an average void fraction of 0.32 (3.4 MPa). However, when you started to use the column the observed pressure drop was 4.5 MPa. a) Determine a single void fraction that would explain this pressure drop. b) Determine a void fraction and fraction of the column length that would explain this higher observed pressure drop.
