Q4: (10 Marks) In order to control the temperature of a jacketed chemical reactor in which an exothermic reaction takes place, an NI-DAQ system with the LabVIEW software is employed. Describe every step which is needed to read the thermocouple output (0-10 mV) and issue a signal to manipulate the cooling water flow rate supplied to the reactor jacket. Use a PID block and describe how to configure it. The desired set-point temperature is 120 C. Draw the Block diagram and the P&ID of this control system. A pneumatic control valve is used to throttle the flow of the cooling water. Make sure to include every component needed and the units of the signals in you diagrams. a Q4: (10 Marks) In order to control the temperature of a jacketed chemical reactor in which an exothermic reaction takes place, an NI-DAQ system with the LabVIEW software is employed.
