A mixing process consists of a single tank that is instrumented, as shown in the figure below. The temperature of stream A varies with time, and the controller attempts to compensate for this by varying the mass flow rate of stream A. The full data of the control system is given below.
For a step change in input pressure, the valve shows first-order behavior, and it requires one minute to settle within 5%.
• Draw a detailed block diagram for the controlled process. Include
➢ the name and units for each of the signals in the block diagram, and
➢ a block for each of the parts of the controlled process.
• Derive a transfer function for each block in your block diagram.
