The age-distribution in a population is more or less variable. Its possible fluctuations are not, however, unlimited. Certain age-distributions will practically never occur; and even if we were by arbitrary interference to impress some extremely unusual form upon the age-distribution of an isolated population, in time the “irregularities” would no ...

The methodology to study the hydraulic age distribution in steady-state perfectly mixed reactors was established by Danckwerts (1953) in his classic work “Continuous-flow Systems.” But the simple equations developed for the steady-state regime are not applicable to nonsteady-state regimes, which are characterized by irregular hydraulic age distribution.
