A copy of POLYMATH is provided on toe CD-ROM for the students to use to solve the homework problems. The example problems that use an ODE solver (e.g., POLYMATH) are referred to as "living example problems because the students can load the POLYMATH program directly onto their own computer in order to study the problem, Stu-...

P6-18b Read the blood coagulation solved problem on the CD-ROMAVeb, Load the blood coagulation Living Example Problem from the CD-ROM. Use part (b) for the complete set of coagulation equations. First verify that you can obtain the curve shown in the shaded Side note on page 325. 

The concentrations exiting the last CSTR are Ci and C, . Equations (E7-7.I) ihiDugh (87-7.15) along with the parameter values are given on %e CD-ROM summary notes and the Polymath living example problem. The Polymath program can be loaded directly from (he CD-ROM so that the reader can vary the model parameters. You can print or view the complete Polymath program and read the complete paper [Alcohol 35 (I). p.iO, 2(X)5] in Summary Notts on the CD-ROM. 

Example 7-6. Load the Living Example Problem, (1) Plot the concentration up to a lime of 24 hours. Did you observe anything unusual If so. what (2) Modify the code to carry out the fermentation in a fed-batch (semibalch reactor) in which the substrate is fed at a rate of 0.5 dm 4i and at concentration of 5 g/dm to an initial liquid volume of 1.0 dm containing a cell mass with an initial concentration of = 0.2 mg/dm and an initial substrate concentration of C,y = 0.5 mg/dm . Plot the concentration of cells, substrate, and product as a function of time along w-ith the mass of product up to 24 hours. Compare your results with (1) above. (.3) Repeat (2) when the growth uncompeiitively inhibited by the substrate with K/ = 0,7 g/dm , (4) Set Cp = 10.000 g/dm- and compare your results with the ha.se ca.se. 

TIte following figures show repressniattve profiles that would result from solving the above < tions. The reader is encouraged to load the Living Example Problem 8-T8-3 and vary a nun of parameters as discussed in P8 -2 (m). Be sure you can explain why these curves look the they do.
