Water in an open dish exposed to dry air at 25oC is found to vaporize at a constant rate of 0.04 g/h-cm2. Assuming the water surface to be at the wet-bulb temperature of ll.0°C, calculate the effective gas-film thickness (i.e., the thickness of a stagnant air film that would offer the same resistance to vapor diffusion as is actually encountered at the water surface).
