Thanks for that Bystander, I did have the figure wrong and from a textbook ("nd hand O.U. textbook) it's 3.6 years. Where the 100 years came from I do not know.
I get the basic derivation of the residence time, what I didn't get was how you'd go about estimating the flux. But even your rough calculations show how wrong the century was.
Notwithstanding my screw up the 3.6 years still dwarves the 11 days for water - which was my original point in stating it.
Thanks again.
