3. Mass Transfer from a Pipe Wall. Air at 52.6 °C and 1 atm abs pressure passes through a pipe with naphthalene
lining. The pipe's diameter in 25 mm. The vapor pressure of naphthalene at 52.6 °C is 1.0 mm Hg. The diffusivity
in air of naphthalene at 0 °C is 5.16x106 m?/s. For a 0.20 m section of a pipe that is lined with naphthalene,
calculate the exiting concentration if the entering air carries 0.001 kgmol/m of naphthalene and has a velocity of
0.30 m/s.

- True or False? Justify your answer. A. In a rectangular drug delivery device that consists of a drug reservoir and a diffusion barrier made of a polymer gel, the steady state diffusion (mass transfer) rate through a barrier of thickness 1 cm was found to be 20 mg/day. If the barrier thickness were to be doubled keeping the reservoir drug concentration the same, the mass transfer rate would be 10 mg/day. B.
