A steady stream of air blows over the top of a cylindrical vessel in which ethyl alcohol is placed at the bottom. The distance between the surface of ethyl alcohol and the top of the container is 1.4m. the prevailing conditions of the temperature and pressure are 30 oC and 1 bar, respectively. Given that the diffusivity of ethyl alcohol at the given conditions is 9.26 2 -1 10 m s , calculate the diffusion rate of ethyl alcohol. State all the necessary assumptions clearly. The vapour pressure of ethyl alcohol at 30 oC is 0.0094 atm.
