Question: E. coli is being grown to a maximum cell density of 140 grams dry cell weight per liter in a bioreactor fitted with a flat blade turbines agitation system (six blades with a w/d ratio of 1/5) that delivers a peak power input of 15 hp/1,000 gallons (gassed). Assume the maximum cell density and maximum agitation speed requirements occur at the same time in the batch cycle. Estimate the total peak heat removal requirement for the fermentation.
