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.
Distance = time * average speed (velocity) Average speed = Distance/time

Time+Time+Time/3=Avarage time.
yes, the average speed equals distance divided by 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.
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.
the hydraulic residence time t is given by t=V/q where V is the volume in the tank and q is the volumetric flow rate. A theoretical residence time can be given by the relationship between concentration and time ln(C)=-(t/tav) where tav in this equation is the residence time.
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.

No, you'll be asked to surrender one. It has happened many time before and none were successful to keep both.

Lambeth Palace is the London residence of the Archbishop of Canterbury but he spends most of his time in Canterbury - sensible man.
Residence time = 3.87E21/310E12 = 1.25E7 years
Yes he does. He has a part time residence there.
The residence time for groudwater is 20,000 years
