Vaporization of water into air in a wetted-wall column, the following data were obtained: Tube diameter= 1.46 cm, Wetted-tube length= 82.7 cm, Air rate to tube at 24oC and 1 atm=720 cm3/s; Temperature of inlet water=25.15 oC, Temperature of outlet water=25.35 oC; Partial pressure of water in inlet air=6.27 torr, and in outlet air= 20.1 torr. DH2O,Air=0.22 cm2/s at 0oC, 1 atm,
(a) Calculate the rate of mass transfer of water in air.(b) Ky for the wetted-wall column.
