Model the complete system in Simulink. The outputs of the system should be the mass fraction of component A. The inputs to the system are w1, w2, x1 and x2. For a step input of w1=500 kg/min and w2= 200 kg/min, and feed compositions (mass fractions) of component A x1=0.4 and x2=0.75, determine the steady state value of x. (show your result on a scope)
