The mass flux from a 5 cm diameter naphthalene ball placed in stagnant air at 40 oC and atmospheric pressure is 1.47 x 10-3 mol/m2 – s. Assume the vapor pressure of naphthalene to be 0.15 atm at 40 oC and negligible bulk concentration of naphthalene in air. If air starts blowing across the surface of naphthalene ball at 3 m/s by what factor will the mass transfer rate increase, all other conditions remaining the same?
