In a test on the vaporization of H20 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, 25.15oC, Temperature of outlet water, 25.3SoC Partial pressure of water in inlet air, 6.27 ton; and in outlet air, 20.1 torr The value for the diffusivity of water vapor in air is 0.22 cm2/s at 0°C and 1 atm. The mass velocity of air is taken relative to the pipe wall. Calculate:

(a) Rate of mass transfer of water into the air

(b) KG for the wetted-wall column
