Mass transfer to the base of an unbaffled cylindrical tank which is agitated by an axially‐mounted impeller is studied experimentally and theoretically. Measured local mass transfer coefficients vary with radial position and fall within theoretical bounds derived for the case of a fluid undergoing solid body rotation above the boundary layer on the base. Average mass transfer coefficients and torque delivered to the base are fitted by consistent theoretical expressions, and an empirical correlation is developed for calculating the average liquid phase mass transfer coefficient.
