A continuous stirred blending process shown below is operating under unsteady state conditions, where liquid volume can change with time. The objective is to blend the two inlet streams to produce an outlet stream that has the desired composition (x = Xsp). The stream 1 is a mixture of two chemical species, A and B. Assuming perfect mixing and constant density, prove that the dynamic model can be written as: = dx w (x1 - x) + (x2-x) W2 Vp dt Vp Control valve Mixture of A and B 11 w1 Pure A - x2 = 1 w2 Overflow line 10
