The estimated residence time of water entering the lake until it leaves is 7.4 years.

In general there's a good correlation between a substance's residence time and its concentration.

The more important it is in sea water, the longer its residence time.

The residence time of the channel is roughly 50 days.

The residence time can then be calculated using the estimated output, if that is known.

This means the residence time for the water in Platte lake is 6 months.

The actual residence times range over many orders of magnitude.

The residence time of Cl in the atmosphere is about 1 week.

Each drug will have a different residence time based on its chemical composition and technique of administration.

The residence time of Cl in the atmosphere is about 2 years.
