A cylindrical stirred bioreactor of diameter and height 2 m has a Rushton turbine one-third the tank diameter in size. The bioreactor contains Newtonian culture broth with the same density as water and with viscosity 4 cP. The tank is now aerated. In the presence of gas bubbles, the approximate relationship between ungassed power number (NP)0 and gassed power number (NP)g is: (NP)g =0.5 (NP)0. What maximum stirrer speed is now possible in the sparged reactor? Estimate the mixing time.
