Question: Consider water in a 2 5 - mm - diameter test tube evaporating into dry air at 1 atm. The distance from the water air

Consider water in a 25-mm-diameter test tube evaporating into dry air at 1 atm. The distance from the waterair interface to the top of the tube is L =15 cm. The mass fraction of the water vapor at the waterair interface is 0.0235, and the binary diffusivity for water vapor in air is 2.6105 m2/s.
A. Determine the mass evaporation rate of the water.
