Packet 3: Bonus 14

The time residence distribution characterizes these devices, which is a delta function in the “plug-flow” type of them. For 10 points each,
[10h] Name these devices. The presence of “dead zones” of stagnant fluid flow in these devices drastically reduces efficiency.
ANSWER: chemical reactors [accept Plug-flow Reactor; do NOT accept nuclear reactor]
[10e] The residence time distribution is a delta function in a PFR as this process doesn’t occur axially. In the lab, this process is commonly done with a rotating magnetic bar to homogenize a solution.
ANSWER: mixing [accept stirring]
[10m] For a CSTR, the time distribution function is proportional to this function of minus t over tau. In the Arrhenius equation’s common form, this operation is applied to minus E-sub-a over R T.
ANSWER: exponential function [accept e to the x or e to the minus x]
