Two Tank System Modelling

Example of two tank system Modelling

2 cstrs in series for a first order reaction, 40% conversion is obtained in the first

CSTR, what is the relative size at second reactor , compared to the first , to

obtain 80% overall conversion ? what is the value of the volume of the tank

to second after a conversion !

ISOTHERMAL CSTRs WITHOUT REACTION

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 !
