A cylindrical stirred bioreactor of diameter and liquid height 2 m is equipped with a Rushton turbine of diameter one-third the tank diameter. The bioreactor contains Newtonian culture broth with the same density as water and viscosity 4 cP. The impeller speed is 146 RPM, and the power number is 5.0. Calculate the power consumption (in kW), Reynolds number and mixing time (in s)
