Problems


1.) A hippo is full grown in 4.5 years. A baby hippo follows its mother around and eats one half of what she eats. However, the rate of digestion in the autocatalytic CSTR stomach, -rAM1, is the same as the mother hippo as is the conversion. Assuming that in the growing stages the hippo stomach volume is proportianal to its age. How old is the baby hippo?
2.) What is the conversion in the intestine (PFR) for the baby hippo diiscussed in Question (1) assuming that Vmax is one half that of the mother?
3.) How would your answers change if the parietal blind sac, the stomach, and the glandular stomach were modeled as three equal volume CSTR's in series whose total volume was .46m3?
4.) What assumptions would change and how would you change them for other models of the hippo's digestive system?
5.) (a) Write five sentances summarizing what you learned from the web module.

(b) The hippo has picked up a river fungus and now the effective volume of the CSTR stomach compartment is only 0.2 m3. The hippo needs 30% conversion to survive. Will the hippo survive?

(c) The hippo had to have surgery to remove a blockage. Unfortunetly, the surgeon, Dr. No, accidentally reversed the CSTR and PFR during the operation. Oops!! What will be the conversion with the new digestive arrangement? Can the hippo survive?

6.) [Chapter 4 Problem] In the wild hippo's migrate along tracts and graze for approximately five hours each night. How would you model the hippo if you assumed it only ate 5 hours out of the day?
