PFR and CMFR at steady state.

a) Determine the volume of a Plug Flow Reactor required to give a treatment efficency of 95% for a substance that decays according to half-order kinetics with a rate constant of 0.05 (mg/L)^1/2/h. The flow rate is steady at 300 L/h and the influent concentration is 150 mg/L.

b) Perform the same mass balance operation for a CMFR reactor and compare the size of the two reactors.
