Modelado de sistemas

Un sistema de tanques en tres diferentes arreglos tienen diferentes concentraciones de sal al inicio de esos tanques reciben un flujo de agua pura a la entrada con un valor de 10 ml/s dado el sistema de tanques encuentre o especifique el menor tiempo para el retiro de la sal en el sistema global.

t|[A]=0 tiempo para cuando la concentracin ? sistema de sal es 0.
a)?1C`A1+CA1=CAi

?2C`A2+CA2=CA1

?3C`A3+CA3=CA2

De las ecuaciones anteriores se obtiene:
C`A1=CAi?1-CA1?1
C`A2=CA1?2-CA2?2
C`A3=CA2?3-CA3?3
C`A1C`A2C`A3= -1?1 0 0 1?2-1?2 00 1?3 -1?3 CA1CA2CA3+ 1?100 CAi
