Question:

Mass flux from a circulating bubble

(a) Use Eq. 18.5-20 to estimate the rate of absorption of CO₂ (component A) from a carbon dioxide bubble 0.5 cm in diameter rising through pure water (component B) at 18°C and at a pressure of 1atm. The following data 3 may be used: D_AB = 1.46 x 10⁵ cm²/s, C_A0 = 0.041 g-mole/liter v_t = 22 cm/s.

(b) Recalculate the rate of absorption, using the experimental results of Hammerton and Garner, 4 who obtained a surface-averaged k_c of 100 cm/hr (see Eq. 18.1-2).
