A tank is filled with 1000 liters of pure water. Brine containing 0.04 kg of salt per liter enters the tank at 9 liters per minu
klemol [59]

Answer:

The differential equation which describes the mixing process is \frac{dc_{salt,out}}{dt} + \frac{2}{125}\cdot c_{salt,out} = \frac{71}{100000}.

Step-by-step explanation:

The mixing process within the tank is modelled after the Principle of Mass Conservation, which states that:

\dot m_{salt,in} - \dot m_{salt,out} = \frac{dm_{tank}}{dt}

Physically speaking, mass flow of salt is equal to the product of volume flow of water and salt concentration. Then:

\dot V_{water, in, 1}\cdot c_{salt, in,1} + \dot V_{water, in, 2} \cdot c_{salt,in, 2} - \dot V_{water, out}\cdot c_{salt, out} = V_{tank}\cdot \frac{dc_{salt,out}}{dt}

Given that \dot V_{water, in, 1} = 9\,\frac{L}{min}, \dot V_{water, in, 2} = 7\,\frac{L}{min}, c_{salt,in,1} = 0.04\,\frac{kg}{L}, c_{salt, in, 2} = 0.05\,\frac{kg}{L}, \dot V_{water, out} = 16\,\frac{L}{min} and V_{tank} = 1000\,L, the differential equation that describes the system is:

0.71 - 16\cdot c_{salt,out} = 1000\cdot \frac{dc_{salt,out}}{dt}

1000\cdot \frac{dc_{salt, out}}{dt} + 16\cdot c_{salt, out} = 0.71

\frac{dc_{salt,out}}{dt} + \frac{2}{125}\cdot c_{salt,out} = \frac{71}{100000}
