A beverage industry
requires some solution of sodium chloride to give a particular flavor to the
drink product. To meet their needs, they mix water with salt . They perform a
dilution to the sodium chloride solution to get a specific concentration they
want. Dilution performed in two CSTRs
isothermally. Each tank has 200 L in volume.
Problem
:
The first tank containing pure water with initial
volume of 50 m3, and then solution of sodium chloride flowing
into the tank with concentration of 0,5 kg/m3
and 2m3/s in flowrate. The
outlet flowrate flow into the second tank with the same flowrate of 1 m3/s.If
the second tank is 5, and the outlet flowrate of the second tank is 1 m3/s.
Determine concentration of sodium chloride solution at t =10 min !
