Problem Statement For the system shown below: $f_1(t)$, $ft^3/min$ $C_{A1}(t)$, $lbm/ft^3$ V $C_A(t)$, $lbm/ft^3$ $f_2(t)$, $ft^3/min$ $C_{A2}(t)$, $lbm/ft^3$ $f(t)$, $ft^3/min$ $C_A(t)$, $lbm/ft^3$ We want to control the outlet concentration $C_A(t)$, $[lb/ft^3]$, by manipulating the most convenient variable. The input variables are the volumetric flows $f_1(t)$ and $f_2(t)$, and concentrations $C_{A1}(t)$ and $C_{A2}(t)$. The volume of the tank is constant, $V = 200.0 ft^3$ and the density of all the streams can be assumed constant and equal to the density of water ($62.3 lb/ft^3$). Also assume perfect mixing so the outlet stream properties are the same as inside the tank. Solve the problem by performing the following steps: a) Develop a mathematical model to obtain the equations that describe the system.

Example 2: assume a sinusoidal $V_{in}$ $V_{in}(t) = V_0 \sin(2\pi f t)$ $V_R(t) = \frac{V_0}{\sqrt{1 + (f_1/f)^2}} \sin[2\pi f t + \tan^{-1}(f_1/f)]$ where $f_1 = 1/(2\pi \tau)$
