A container, which is wrapped in a fabric that is continually moistened with a highly volatile liquid, may be used to keep beverages cool in hot, arid regions. Suppose that the container is placed in dry ambient air at 40°C, with heat and mass transfer between the wet- ting agent and the air occurring by forced convection. The wetting agent is known to have a molecular weight of 200 kg/kmol and a latent heat of vaporization of 100 kJ/kg. Its satu- rated vapor pressure for the prescribed conditions is approximately 5000 N/m2, and the diffusion coefficient of the vapor in air is 0.2 X 10-4 m2/s. What is the steady-state temperature of the beverage?
