Problem 7-23AA CSTR is being operated at steady state. The cell
growth follows the Monod
growth law without inhibition. The exiting substrate and cell
concentrations are measured as afunction of the volumetric flow
rate (represented as the dilution rate), and the results are
shownbelow. Of course, measurements are not taken until steady
state is achieved after each change in
the flow rate. Neglect substrate consumption for maintenance and
the death rate, and assume that
Yp/c is zero. For run 4, the entering substrate concentration
was 50 g/dm3and the volumetric flow
rate of the substrate was 2 dm3/s.
Run Cs (g/dm ) D (day-
) Cc (g/dm )

(a) Determine the Monod growth parameters max andKs.
(b) Estimate the stoichiometric coeficients, Yc/sand Ys/c.
(c) List ways you can work this problem incorrectly.(d) How
could you make this problem more difficult?
