1. Two reactors, one of them a CMBR and the other a CSTR, are
operating side by side in parallel. Each is treating one half of a
total flow rate of 800 gal/min containing a substance that enters
at a concentration of 80 mg/L and experiences first-order
degradation with a k value of 0.1/min.
The reactors have identical volumes of 8000 gal, so they also
have equal liquid retention times of 20 min.
(a) What is the concentration of the...
