The average residence time is a measure of the time it takes for the total stock or supply of the material to be cycled through a system. To compute the average residence time (T; assuming constant size of the system and constant rate of transfer), we take the total size of the stock (S) and divide it by the average rate of transfer (F) through the system: T=S/F.
Example if a reservoir holds 100 million cubic meters of water, and both the average input from streams entering the reservoir and the average output over the spillway are 1 cubic meter per second, then the average residence time for a cubic meter of water in the reservoir is 100 million seconds, or about 3.2 years.

What is the formula to find the average speed of a given distance and time?
Distance = time * average speed (velocity) Average speed = Distance/time
Which of these involves renting a residence for a specific amount of time such as six months one year or even five years?
lease
Which Involves renting a residence for a specific amount of time such as six months one year or even five years?
lease
How do you calculate an average time?
Time+Time+Time/3=Avarage time.
Is the average speed equal to distance divided by time?
yes, the average speed equals distance divided by time
What is the formula for calculating residence time?
The formula for calculating residence time is: Residence time = Volume of the system / Flow rate of the system. This formula helps in determining the average amount of time a substance will spend in a system or a reactor.
What is Difference between residence time and space time?
Residence time is the time it takes a particle to complete the cycle. Space time is volume of the reactor over the velocity. If the volume does not change and the velocity remains constant then Residence time = space time, however, if there is a disturbance in the reactor (i.e., change in pressure, temp, ect.), then residence time does not equal to space time.
What is residence time of CO2?
Residence time of CO2 refers to the average amount of time a molecule of CO2 remains in the Earth's atmosphere before being removed by natural processes. It is estimated to be around 4 to 5 years.
What is the residence time of water in the atmosphere?
The residence time of water in the atmosphere is around 9 days on average. This means that water molecules remain in the atmosphere for about 9 days before returning to Earth as precipitation.
The average length of time the various salts remain in the ocean before cycling out of the ocean is known as the time?
The average length of time the various salts remain in the ocean before cycling out of the ocean is known as the residence time. This is also known as the removal time.
Do chemicals have the shortest average residence time in the biosphere lithosphere hydrosphere or atmosphere?
Chemicals generally have the shortest average residence time in the atmosphere. This is because they can be quickly dispersed or degraded by various atmospheric processes such as photolysis and chemical reactions. In comparison, chemicals may reside longer in the biosphere, hydrosphere, or lithosphere depending on their properties and interactions with the environment.
What is the residence time of water in air?
The residence time of water in air is typically around 9 days. This means that, on average, a water molecule will remain in the atmosphere for about 9 days before either being deposited back onto the Earth's surface as precipitation or being absorbed by vegetation.
What is residence time of gas?
Residence time in the boiler is typically two to five seconds, and the particles must be small enough for complete combustion to have taken place during this time. The ratio of gas occupied to a particular volume is called residence time based on gas.
Which has the longest residence time on continents?
Methane has the longest residence time on continents among the greenhouse gases, due to its lower reactivity and slower rate of removal from the atmosphere.
What is a typical residence time for a stream in Ohio?
14 days
Is it legal to have an American residence permit and a Canadian residence permit at the same time?
No, you'll be asked to surrender one. It has happened many time before and none were successful to keep both.
Whose official residence is Lambeth Palace in London?
Lambeth Palace is the London residence of the Archbishop of Canterbury but he spends most of his time in Canterbury - sensible man.
