Question:

According to a brochure from Dow Chemical Company, the pressure drop for water flowing through a bed of 20-mesh to 50-mesh Dowex 50-X8 resin is said to be proportional to the flow rate and has a value of 0.80 (lbƒ/in.2)/ft at a flow rate of 10 gal/min · ft2

(a) Predict the pressure drop, using an arithmetic average particle size and a void fraction of 0.35. 

(b) What average particle size or alternate value of void fraction would be needed for agreement with the published pressure drop?
