###### Question details

Calculate the maximum rate of absorption of oxygen of a fermenter from air bubbles at T=37º C and Ptot= 1 atm absolute to water with zero dissolved oxygen . The bubbles have a diameter of 100 micrometer. The solubility of O2 in water at 37º C is 2.26 x 10-7 gmol O2 /cm3 liquid or 2.26 x 10-4 kmol/m3 O2 /m3 . The diffusivity of oxygen in water at 37º C is 3.25 x 10-9 m2 /sec.
