In the absorption of component A from an airstream into an aqueous stream, the bulk compositions of the two adjacent streams were analyzed to be PAG = 0.1 atm and CAL = 0.25 lbmole/ft3. The Henry’s law constant for this system is 0.265 atm/(lbmole A/ft3 of solution). The overall gas phase mass transfer coefficient , KG, was equal to 0.055 lb mole A/hr.ft2.atm. If 57% of the total resistance of mass transfer is encountered in the gas film, determine

1 the gas-film mass transfer coefficient, kG,
2 the concentration on the liquid side of the interface, CAi,
3 the liquid-film mass transfer coefficient, kL,
4 the mass flux of A, NA,
