The airbubbles are assumed to be spheres, each having a radius of1.0 mm, and are in thermal equilibrium with water at 298 K.Determine how long the bubble should remain in the water toachieve a vapor concentration at the center that is 90% of themaximum possible (saturation) concentration. Assume that theair is dry when it enters the column of water and that the airinside the small bubble is stagnant. The vapor pressure of waterversus temperature is available from many sources, including thesteam tables.
