Consider the two stirred tank heaters shown in the picture below. 2.1 Identify the state variables of the system. 2.2 Determine what balances you should perform. 2.3 Develop the state model that describes the dynamic behaviour of the process, assuming that the heats of solution are strong functions of the composition.
Consider the two stirred tank heaters shown in the picture below.
2.1 Identify the state variables of the system.
2.2 Determine what balances you should perform.
2.3 Develop the state model that describes the dynamic behaviour of the process, assuming that
the heats of solution are strong functions of the composition.
2.4 How is the model simplified if the heats of solution are very weak functions of the
composition?
Assume that the flow rates are volumetric, and the compositions are in moles per volume. The
effluent flow rates are proportional to the liquid static pressure that cause their flow. A1 and A2
are the cross-sectional areas of the two tanks and At is the heat transfer area for the steam coil.
