"WitrynaThe mass transfer rate is an important variable in the rate-based model. The most important variables in the mass transfer model are the diameter of the bubble and the bubble rising velocities. The lower the bubble rising velocity, the smaller the mass transfer rate is, and less variation in the compositions of methanol is obtained. " - Importance of mass transfer
