Question:
Estimate the liquid-film mass-transfer coefficient for O2 diffusing from an air bubble rising through water at 20°C. Choose a bubble size of 4.0 mm, assume a spherical shape, and assume rapid circulation of gas inside the bubble. Neglecting the change of bubble size with distance traveled, calculate the fraction of oxygen absorbed from the air in 1 m of travel if the water contains no dissolved oxygen.
