2. A simple mixing process follows first-order behavior. A 200-gal mixing tank process, initially at steady state, is shown in Fig. At time , the inlet flow is switched from salt to freshwater. What does the inlet flow rate need to be to reduce the exit concentration to less than in (5Marks)
Expert Answer
Inlet flow rate was given belowTo determine the inlet flow rate required to reduce the exit concentration to less than 0.5% in 30 minutes, we need to use the first-order kinetics equation for the mixing process, which is given as:C(t) = C0 * e^(-kt)where C(t) is the concentration at time t, C0 is the initial concentration,
