An exothermic reaction takes place in a jacketed CSTR as illustrated in Figure below The reactor temperature control configuration includes feedback (P only) control on the jacket temperature cascaded inside the feedback control (PI) on the reactor temperature, with feedforward control combined with the outer feedback loop to reduce the impact of disturbances in the feed temperature.

A). what is the manipulated variable of the inner feedback loop?

B). Reading P&ID is skill a process control engineer should possess. Draw the bloclk diagram for the system. On the block diagram, label all variables according to the notation in the drawing. All sensors, disturbances, set points, controllers, valves, processes, and outputs shown in the drawing should appear in the block diagram.
