Size (calculate height and diameter) a bioreactor (a pressure vessel) that can hold 2000L working liquid volume. Assum e 78% of the bioreactor total volume can be filled with liquid, with 22% of the bioreactor total volume left for gas holdup and headspace. Assume the optimal mass transfer and mixing design gives a vessel H/D ratio of 1.9. Model as a cylinder and neglect the volume/height of the vessel heads. (Hint: you don't actually have to look up anything about bioreactors! This should be a VERY simple calculation using only geometry...) Bioreactor height (neglecting heads) Bioreactor diameter: feet feet
