For mixed flow of a mixture of sizes of unchanging size particles, the mean residence time of a material of a given size is ____

For mixed flow of a mixture of sizes of unchanging size particles, the mean residence time of a material of a given size is ____ Correct Answer t = \(\frac{Weight \, of \, all \, solids \, in \, the \, reactor}{Feed \, rate \, of \, solids \, to \, the \, reactor} \)

The mean residence time of a material of a given size is equal to mean residence time of solids in the bed. It is the fraction of weight of all solids in the reactor to the feed rate of solids in the reactor.

The critical reasoning question is based on a short argument, a set of statements, or a plan of action. For each question, select the best answer of the choices given. The size of particles is directly linked to their potential for causing health problems. Small particles less than 10 micrometers in diameter cause the greatest problems, as they can get deep into the lungs and some may get into the bloodstream. One being exposed to such particles can affect both the lungs and the heart of a person. But there are particles that are causing environmental effects too, few of which are given below.  Which among the following below options does not talk about the effects of these particles on the environment?
