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 (N_P)₀ and gassed power number (N_P)g is: (N_P)g =0.5 (N_P)₀. What maximum stirrer speed is now possible in the sparged reactor? Estimate the mixing time.
