A semiquantitative estimation of residence time distribution has been done using a colored masterbatch tracker (50 mg) that has been dosed from main hopper at a certain instant: the times at which the appearance of color at die exit (min residence time) and its disappearance (max residence time) occurred have been registered.

1969) and Sandberg and Sjoberg (1983) introduced the concept of residence time distribution from chemical engineering (Nauman 1981) to indicate passive contaminants dispersion and air diffusing efficiency, which depends on indoor airflow characteristics (Robinson and Tester 1986).
Combing" or other similar distributive mixing elements are often specified, and the feed rate versus TSE screw rpms manage the residence time and residence time distribution to facilitate that required for the reaction (figure 2).
A thermal process for the potato soup was established in three steps: * determining Residence Time Distribution (RTD) of particles, * mathematical modeling of lethality for the fastest particle, * validation of the model with an inoculated pack study.

This new edition extends these aims to include additional chapters dealing with prediction in ungauged basins, predicting residence time distributions, predicting the impacts of change and the next generation of hydrological models.
Since all material elements do not necessarily spend the same period of time in the extruder, residence times have a distribution, called residence time distribution (RTD).
This results in a short residence time and a narrow residence time distribution.
