The residence time of a lake is defined as the volume of the water in the lake divided by the discharge into or out of the lake. Letting the volume of water in the lake be V and the discharge to and from the lake be Q, The residence time Tr is. (A comment on the discharge here: this is easy to deal with only for stream discharge, not for ...

The retention time assures that equilibrium between the liquid and gas has been reached at separator pressure. The retention time in a separator is determined by dividing the liquid volume inside the vessel by the liquid flow rate. The retention time usually varies between 30 seconds and 3 minutes.

The residence time is the characteristic time that a parcel of water will remain within a water body. The quantitative definition of "residence time" varies in the literature (Monsen et al., 2002). Generally, it is implied that a complete exchange of the water does not occur in this time. For this reason, the residence time is sometimes ...

The residence time distribution of a reactor is an abstract concept to most chemists. In batch chemistry, residence time is simple – you add reactants and remove products. The time chemicals spent in the reactor is the residence time. In a continuous flow system, however, there is rarely a single "time" the molecules spend in a reactor.
