A gas absorption tower of diameter 2 m contains ceramic Raschig rings randomly packed to a height of 6 m. Air containing a small proportion of sulphur dioxide passes upwards through the absorption tower at a flow rate of 6 m3/s. The viscosity and density of the gas may be taken as 1.80 x 10-5 Pa.s and 1.2 kg/m3, respectively. How much is the laminar flow component of the Ergun equation? For the Ceramic Raschig rings: surface area per unit volume of packed bed, SB = 180 m2/m3, voidage of randomly packed bed = 0.71 a. 2.08% b. 7.02% c. 7.92% d. 1.98% e. None of these
