##### Reference no: EM13317197

Seawater flows steadily into an open 100 liter tank initially filled completely with freshwater. The freshwater mixes thoroughly with the seawater and the mixture overflows out of the tank. If the flow rate out of the tank is 10 liters/minute, determine the time (in seconds) to obtain a density of 1010 kg/m^3. Assume freshwater is 1000 kg/m^3, and seawater is 1030 kg/m^3.
