Consider an Arnold cell (cylindrical tube) with cross sectional area of 10 cm2 and height of 30 cm. Initially it contains a 10 cm liquid column of acetone (58.08 g/gmol) and saturation vapor pressure of 30 kPa at ambient conditions (20 degree C). The diffusion coefficient of acetone vapor in air is 0.11 cm2/s. Estimate the flux and mass transfer rate associated with acetone evaporation in molar and mass units. State and justify your assumptions
