Chapter 7, Problem 7.132(choose chapter or problem)
Mass transfer experiments have been conducted on anaphthalene cylinder of 18.4-mm diameter and 88.9-mm length subjected to a cross flow of air in a low-speedwind tunnel. After exposure for 39 min to theairstream at a temperature of 26?C and a velocity of12 m/s, it was determined that the cylinder massdecreased by 0.35 g. The barometric pressure wasrecorded at 750.6 mm Hg. The saturation pressure psatof naphthalene vapor in equilibrium with solid naph-thalene is given by the relation psat?p10E, whereE?8.67?(3766/T), with T(K) and p(bar) being thetemperature and pressure of air. Naphthalene has amolecular weight of 128.16 kg/kmol.(a) Determine the convection mass transfer coefficientfrom the experimental observations.(b) Compare this result with an estimate from anappropriate correlation for the prescribed flowconditions
