0 (Mass transfer). The cylindrical object shown in Figure P 10.20 is covered by a layer of naphthalene. The surface of the cylinder is at 50°C, while the surrounding air is at 20°C. Calculate the heat transfer rate and the total rate of naphthalene released into the air. The air is dry and stagnant.
