Salty water flows steadily into an open 1000 liter tank initially filled completely with fresh water.
The salt water mixes thoroughly with the fresh water and the mixture overflows out of the tank. If the flow rate out of the tank is 60 liters/minute. Assume freshwater is 1000 kg/m^3, and the salty water is 1020 kg/m^3.
Determine the time (in seconds) to obtain a density of 1005 kg/m^3 ?
