11. A packed bed of spherical ion-exchange resin particles (0.75 mm diameter) is used to purify water. The bed has a porosity of 0.33. The superficial velocity is 0.6 m/s, and the bed column is 1 m tall. The density of water is 1000 kg/in³ and the viscosity is 1 cp. Calculate the pressure drop required to operate the packed 3 bed. Assume gravity contribution to friction energy term is negligible. (Hint: first determine whether the flow is laminar or turbulent).
