question

Carbon dioxide from an aqueous solution has to be removed by an air stream flowing at 3.0 ft/sec using 3 in. internal diameter wetted wall column. At one point in the column the CO_2 concentration in air stream is 1 mole percent and in the water is 0.5 mole percent. If the column is operated at 10 atmand 80°F, find the gas-phase mass transfer coefficient and the mass flux at that point in the column.
