a volatile organic compound (c6h6) costing rs. 5 a kg is stored in a tank 10 m diameter and open at the top. a stagnant air film 10 mm thick is covering the surface of the compound beyond which the compound is absent. if the atmospheric temperature is 25 0c, vapor pressure of compound 150 mm hg and its molar diffusivity 0.02 m2 / hr, calculate the loss in rs./ day. from bartley by
