In a two-stage chemostat system, the volumes of the first and second reactors are V1 = 500 I and V2 = 300 I, respectively. The first reactor is used for biomass production and the second is for a secondary metabolite formation. The feed flow rate to the first reactor is F = 1001/h, and the glucose concentration in the feed is S = 5.0 O. Use the following constants for the cells:

a. Determine cell and glucose concentrations in the effluent of the first stage. b. Assume that growth is negligible in the second stage and the specific rate of product formation is q _p = 0.2 g P/g cell h, and Y _p/s = 0.6 g P/g. Determine the product and substrate concentrations in the effluent of the second reactor
