Question: 2. 9b. Mase transfer from a flat plate A 1-m square thin plate of solid naphthalene is oriented parallel to a stream of air flowing

2. 9b. Mase transfer from a flat plate A 1-m square

2. 9b. Mase transfer from a flat plate A 1-m square thin plate of solid naphthalene is oriented parallel to a stream of air flowing at 20m/s. The air is at 330K and 101.3kPa. The naphthalene remains at 290K; at this temperature the vapor pressure of naphthalene is 26Pa. Estimate the moles of naphthalene lost from the plate per hour, if the end effects can be ignored. Answer: 1.86mol/h
