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.

- Two liquids of different densities (ρ 1 = 1550 kg m /m 3 and ρ 2 = 550 kg m /m 3 ) are poured together in acylindrical container 0.5 m in diameter x 1 m height.

The heat transferred (q) depends on a heat transfer coefficient (h) for the flask material, the temperature difference (∆T) across the flask wall, and the commonly “wetted” area (A) of the flask and bath, q = hA∆T. When an exothermic reaction is run at a given T, there is a bath temperature at which the reaction can no longer be controlled, and the reaction “runs away” suddenly. A similar problem is often seen when a reaction is “scaled up” from, say, a half-filled small flask to a half-filled large flask. Explain these behaviors.arrow_forwardSolve 4th onlyarrow_forward
