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. If the specific power consumption must not exceed 1.5 kW m^-3, determine  the maximum allowable stirrer speed. What is the mixing time under these conditions?  __________

cells are grown in a CSTR a steady state at two dilution rates 0.1 h^-1 and 0.5h^-1 and the steady state concentrations are as follows: 

if the inlet substrate concentration is 20 g/I, the cells follow monod growth kinetics and product formation kinetics is modelled as a both growth associated and non growth associated kinetics given by the equation then answer the following questions, the best estimate of maximum specific growth rate is:
