Consider the two stirred tank heaters shown in Figure PII.3. (a) Identify the state variables of the system. (b) Determine what balances you should perform. (c) Develop the state model that describes the dynamic behavior of the system. (d) How would you express the heats given by the two steam flows in terms of other variables? The flow rates of the effluent streams are assumed to be proportional to the liquid static pressure that causes the flow of the liquid. The cross- sectional areas of the two tanks are A, and A2 (ft) and the flow rates are volumetric. No vapor is produced either in the first or the second tank. An and A12 are the heat exchange areas for the two steam coils.
