A packed bed is composed of cubes 0.02 m on a side and the bulk density of the packed bed is 980 kg/m3. The density of the solid cubes is 1500 kg/m3.

a.) Calculate the void fraction (ε) and effective diameter (Dp).

b.) What is the void fraction if the cubes are replaced with cylinders that have a diameter 0.02 m and a height 0.02 m, all other parameters remaining the same?
