A radioactive tracer, with a half life of 10 days, is injected into an underground aquifer at t = 0. Eighty-five days later the radioisotope is first observed in a monitoring well 500 m from the injection point. What is the speed of water flowing in the aquifer between the two wells?

Answer #1

A radioactive tracer, with a half life of 10 days, is injected into an underground aquifer at t = 0.

Eighty-five days later the radioisotope is first observed in a monitoring well 500 m from the injection point.

Distance, d= 500 m

To determine : The speed of water flowing in the aquifer between the two wells.

Now,

We know that Speed is the distance traveled per unit of time.

Therefore the speed of water flowing in the aquifer between the two wells is 5.88 m/s.
