Question

Problem 10 Situation: In a water softener, water trickles down through a bed of spherical, ion-exchange, resin particles each 0.03 [in] in diameter. The bed has a vold fraction of 0.33. The water is kept at a level that is 0.25 [ft] above the top of the bed. The dimensions of the packed section are 2 [in] in diameter and 1 [ft] in length. Requirements: Please, find the flow rate of water through the column, in [cm2/s]. Problem 11 Ans.: 7-35 [cm3/s Requirements: Please, estimate the pressure drop and water level above the column required in the previous problems to get a superficial velocity of 2 [t/s). Ans.: 86 [psi]
