In the absorption of component A (molecular weight = 60) from an airstream into an aqueous solution, the bulk compositions of the two adjacent streams at a point in the apparatus were analyzed to be pA,G = 0.1 atm and CA,L = 1 .O kmol of A/m3 of solution. The total pressure was 2.0 atm; the density of the solution was 1100 kg/m3. The Henry’s constant for these conditions was 0.85 atm/mole fraction. The overall gas coefficient was K, = 0.27 kmol/m2- h-atm. If 60% of the total resistance to mass transfer resides in the gas film, determine:
(a) The gas-film coefficient, kG
(b) The liquid-film coefficient, kL,.
