Fig. (5) Net pressure drop model validation and sensitivity analysis results. Panel a: in-vitro (grey line) and predicted net pressure drop (red line: present Δp_net model; green line: model given in [19]. = 1.731 cm² for both models). Panel b: grey and red lines as in panel a; blue lines: Δp_net as predicted by the present model for = 1.558 cm² (upper line) and = 1.904 cm² (lower line), respectively in-vitro data are taken from [19].
