Volatile pure solid slab sublimes into an air stream flowing by bulk velocity of 2 m/s over the slab with an exposed cross sectional surface area of 1x10^-3 m². The air stream is following at 25 ^oC and atmospheric pressure. Given the average mass transfer coefficient, k_c for to sublimation of the volatile solid into the air is 0.12 m/s and the vapor pressure of the volatile solid at 25 ^oC is 4.74x10³ Pa, calculate the sublimation rate of the volatile solid into the air stream.
