The exit age distribution curve E(t) for an ideal CSTR with the average residence time, η, is given by__________________?
Correct answer: B. e-t/η/η
- A. e-t/η
- B. e-t/η/η
- C. 1 - e-t/η
- D. 1 - (e-t/η/η)
Explanation
An ideal CSTR has an exponential residence-time distribution, E(t) = (1/η) exp(-t/η), where η is the mean residence time. The factor 1/η is required so that the area under E(t) equals one.
