A salt lake has no outlet i.e., the inlet flow is completely balanced by evaporation. The lake has a volume of 2.5 x 1011 m3 and the concentration of salt in the lake is 52 g/L. The inlet stream to the lake has a concentration of 0.18 g/L and is flowing at a rate of 3.7 x 109 m3/yr. If the lake initially had a concentration of 0.18 g/L and the outflow abruptly stopped, how long ago did that occur?

A salt lake has no outlet i.e., the inlet flow is completely balanced by evaporation. The lake has a volume of 2.5 x 1011 m3 and the concentration of salt in the lake is 52 g/L. The inlet stream to the lake has a concentration of 0.18 g/L and is flowing at a rate of 3.7 x 109 m3/yr. If the lake initially had a concentration of 0.18 g/L and the outflow abruptly stopped, how long ago did that occur?
