The flow-rate into a lake will be 3,000,000,000 liters per day and flow-rate out is 3,000,000,000 liters per day. The concentration of contaminant in the water flowing in is 0.0001mg/L. The initial volume of the lake is 737,040,000,000 million liters with a current mercury concentration of 0.8 mg/Liter of water. How much time until contaminant levels to drop to 0.0005mg / Liter once the dams have been opened to full capacity. (Assume evaporations rates, ground water recharge nor other environmental conditions do not affect your model.)

Question
The flow-rate into a lake will be 3,000,000,000 liters per day and flow-rate out is
3,000,000,000 liters per day. The concentration of contaminant in the water flowing in is
0.0001mg/L. The initial volume of the lake is 737,040,000,000 million liters with a current
mercury concentration of 0.8 mg/Liter of water.
How much time until contaminant levels to drop to 0.0005mg / Liter once the dams have
been opened to full capacity. (Assume evaporations rates, ground water recharge nor other
environmental conditions do not affect your model.)
