Consider the tank heater system shown in the figure. A liquid enters the tank with a flow rate Fi and a temperature Ti, where it is heated with steam. Let F and T be the flow rate and temperature of the steam leaving the tank. The tank is considered to be well stirred, which implies that the temperature of the effluent is equal to the temperature of the liquid in the tank. Explain briefly how you suppress the influence of external disturbances in this case with a neat sketch.
