Question: 2. The molar mass transfer rate from a 30 mm diameter and 5mm length naphthalene MAN wwwwwwwwwwww cylinder placed in stagnant air at 85.8 C

2. The molar mass transfer rate from a 30 mm diameter and 5mm length naphthalene MAN wwwwwwwwwwww cylinder placed in stagnant air at 85.8 C and atmospheric pressure is 2x10-7 kmol/s. If wwwww www air starts flowing across the surface of naphthalene with a velocity of 3 m/s, by what wwwwwwNNANAR wwwwww.bean www factor will the mass transfer rate increase, all other conditions remaining the same? At wwwwwww vinnnn www wwwwwwwwwww..chawww..ma wwwww 85.8 C vapor pressure of naphthalene is 13.3 mbar, the viscosity and density of air are wwwwwwwwwa wanavansnatu AMMA WAWA www sannansw 2.1x105 kg/m.s and 0.974 kg/m. Assume that bulk concentration of naphthalene in air wwwwwwwwwwwwwwwwwwwwwwwwwwwwwww wwwwwwwwww derivations and assumptions!! MANN MAN is negligible 2cm away from the center of naphthalene cylinder.
