A baffled fermenter with tank diameter and liquid height equal to 1.2 m is stirred using a six-blade downward-pumping impeller. The impeller diameter is 0.42 m and the stirrer speed is 1.5 s. The viscosity of the fermentation broth is 10-2 Pa s and the density is 1000 kg m-3. Estimate the mixing time under nonaerated conditions.

Precision will be reduced, but yield will be increased
Optimisation of a PCR reaction is often a compromise between the competing demands for precision, efficiency and yield. Although the specific effects may vary, generally, increasing the annealing temperature will increase non-specific primer binding and reduce precision. Increasing the length of the elongation phase will reduce the proportion of incomplete newly-synthesised strands and therefore increase yield. In this case, the potential effect on efficiency is unclear. Increasing the elongation phase would increase the reaction time, but the time taken to ramp down to a lower annealing temperature would be reduced.
