Pure water at 26.1 °C is flowing at a rate of 0.0701 ft³/h through a packed bed of 0.251-in benzoic acid spheres having a total surface area of 0.129 ft². The solubility of benzoic acid in water is 0.00184 lbmol benzoic acid/ft³ solution. The outlet concentration CA2 is 1.80 x 104 lbmol/ft³. Calculate the mass transfer coefficient Ke.
