14:36 B () 163 QUESTION 2 2.1 Figure below depicts a continuously stirred tank reactor (CSTR) heater in which the control objective is to keep the exit temperature $T_r$ at a set point $T_r$. The inlet liquid stream has a mass flow rate $\dot{m}$ and a temperature $T_i$. The reactor contents are well stirred and heated by an electrical heater that provides $Q$ watts. It is assumed that liquid density remains constant, the inlet and outlet flow rates are identical, and that the temperature variations are small enough that the temperature dependence of density can be neglected. Under these conditions the volume $V$ of liquid in the reactor remains constant. $T_i$ $\dot{m}$ $M$ $V$ $Q$ Heater $T_r$ $\dot{m}$ 2.1.1 Identify the process, manipulated and disturbance variables. (3) 2.1.2 Identify control objectives (2) 2.1.3 Identify output variables and classify these as (a) measured or (b) unmeasured.
