Q4/ A vertical water softener column of 1.65 m diameter is packed to a height of 3.55 m with 9.5 ton ion- exchange resin 2.375 sp.gr cylindrical particles of 1.65 mm average diameter and 3.55 mm height. Calculate the void fraction (e) and the pressure drop of water flows over the fixed bed at a rate 220 m³/h? Could this water at 1 atm, across the bed due to gravity (i.e. without pump)? What the power of the pump (n =0.62) must be used in order to pump the water across the softener when it is flow downward (if it is required a pump) and when it is flow upward. For water p =1000 kg/m³ μ = 1 cP
