Question

Clearly show all assumptions and calculations. Situation: A vertical packed bed of solid particles of density 2500 [kg/m3], occupies a depth of 1 [m] in a vessel of cross-sectional area 0.04 [m2]. The mass of solids in the bed is 50 [kg] and the surface-volume mean diameter of the particles is 1 [mm]. A liquid stream flows upwards through the bed at a rate of 1.44 [m3/h]. Relevant Properties: Density and viscosity of the liquid are 800 [kg/m3] and 2.0 [mPa·s]. Requirements: Please, do the following: (a) Show that: f = ((150 + ?(22,500 + 7 Ká²)) / (2 Ká))² (7 points) (b) Estimate the void fraction of the bed. (5 points) (c) The pressure drop across the bed, in [kPa]. (15 points) (d) The volume flow rate if the pressure drop is increased to 20 [kPa]. (12 points)
