Sketch the P&ID and the block diagram of the experimental setup to be used in

the lab component of this course, which is located in SEB $1081.$

Please clearly describe the process identifying the manipulated variable, the

disturbance and the controlled variable. On the block diagram mark the nature of

the signal around the control loop, i$.$e$.C,$ flow rate, $0-5V,3-15g,$ etc. On the

block diagram, show the computer where the PID controller resides $($LabView$),$

and the Data Acquisition $($DAQ$)$ system.

Assuming that the control valve is air$-$to$-$open $($Fail Close, FC$),$ determine if the

controller is Direct or Reverse acting.

An exothermic reaction is carried out in a stirred tank reactor. Cooling water is

supplied to the reactor jacket to avoid reaction run$-$away conditions. Determine

the control valve action $($fail open or fail close$)$ and the controller action $($direct$-$

acting or reverse$-$acting$).$
