Assignment #1.1 (4%) From the CSTR system such as that in chapter 2, consider two isothermal CSTR in series, each tank installed the overflow pipes as discharge. The inlet flow rate into the first tank is 0.085 m/min with the initial inlet concentration is 0.925 mole/m and the liquid volume of both tanks are 1.05 m. Given the chemical reaction is first-order with k = 0.040 min? a) Determine the dynamic response to a step change in inlet concentration. b) Plot the concentration of liquid in both tanks in response to the step change in inlet concentration using MATLAB Assignment #1.2 (4%) In heating air for a living room, air temperature is controlled by a feedback control system with an on-off air heater. Dimension of the room is 5 by 5 by 3 m with the initial room temperature of 20 C and the initial heater status is off. The outside temperature is 10 C The air heater switches on instantaneously at 17 C and off at 23 C i.e. the heater capacity is Process Dynamic Control KMUTNB 2/2564 Karn Pana-Suppamassadu - either 0 (off) or 1.5x100 (on) cal/hr. The overall heat transfer coefficient UA = 45x10' callC hr). Given the heat capacity and density of air are 0.17 cal(gC) and 1,190 g/m", respectively. a) Determine the dynamic response of the room temperature. b) Plot the room temperature corresponding to the heater status (heat capacity) using MATLAB
