Consider the scale up of a fermentation from a 10L to 10000L while maintaining geometric similarity. Agitation speed was maintained at 500 rpm in the 10L fermenter. If scale up is done based on constant tip speed, then the agitation speed in the larger reactor should be 

rpm.

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.
