The second stage of the design process is to evaluate the oxygen requirement for the organism. This is necessary so that we can establish if the vessel we construct will be capable of attaining the biomass concentration we require. Calculate the maximum oxygen uptake rate given the following information:

maintenance requirement for oxygen is 0.04 g (oxygen) g^-1 (biomass) hr ^-1

You will find it necessary to establish the physical characteristics of the vessel first. It is best to complete the entire mechanical design for later sections where this information is required. For the physical dimensions ensure that you calculate/specify:

(i) vessel height and diameter

(ii) impeller diameter

(iii) liquid height

(iv) impeller type and locations

v) number, size and position of baffles
