3) A thin layer of liquid benzene, C6H6, flows down the outside surface of a vertical plate 1.6 m wide by 3.5 m long. The temperature of the liquid is 310 K. At 310 K and 1 bar pressure, benzene-free nitrogen flows at a rate of 6 m/s across the width of the plate parallel to the surface. Because the benzene content is relatively high, at least at the film's inner edge (0.14 mole fraction). Calculate how much liquid should be provided at the top of the plate such that evaporation only keeps it from reaching the bottom. At 310 K, liquid benzene has a density of 0.9 g/cm³. At 310 K and 1 bar, the film's typical characteristics are p = 1.3 kg/m³, u-1.61 * 10-5 pa.s, and DAB=0.099 cm²/s
