Figure 1 shows a schematic diagram of a flash drum. Steam in the steam coil is used to vaporize part of the liquid feed, and the liquid product is removed by the pump. There are 5 control valves installed to the flash drum. Determine a suitable manipulated variable and a control valve (1-5) that can be used in the feedback control system to achieve the following control objectives: i. The pressure of the vessel and the inlet steam flow rate Please draw a complete P&ID of the feedback control loop (including transducer) for both control objectives.
