Residence Time of Water

A stable and highly soluble pollutant is dumped into a lake at the rate
of 0.19 tonnes per day. The lake volume is 2E7 m3 and
the average water flow-through rate is 8E4 m3 per day. Ignore evaporation
from the lake surface and assume the pollutant is uniformly mixed in the lake.
What eventual steady-state concentration will the pollutant reach (in ppm)?

Hint: Calculate residence time of water in lake. Multiply by pollutant input rate.
