3.8 An extension of Textbook mixing tank Example 3.1 

Assume that the solvent, and component A are contained in separate tanks; sketch the extra equipment which would have to be added to Figure 3.1 in order to achieve the desired value of C_{A0}. 
3.9 An extension of Textbook CSTR Example 3.2 

3.10 An extension of Textbook series CSTRs Example 3.3 

From the derived model of the two isothermal CSTR reactors in series, which variable C_{A1} or C_{A2}, responds faster to a step change in C_{A0}. Why is this the case? 
3.11 An extension of Textbook Example 3.4 

Consider the performance of an onoff residential heating system, in which feedback control is used to monitor and control the temperature. What would be the effect on the dynamic behavior if: 
3.12 An extension of Textbook Example 3.5 

Consider an isothermal CSTR, with a second order chemical reaction. Under what scenarios is the linearized model likely to be very accurate? 
3.13 An extension of Textbook draining tank level Example 3.6 

At first glance, there appears to be an error in Figure 3.14 b. How can the linearized model predict a negative level in a tank? 
3.14 An extension of Textbook Example 3.7 

3.15 An extension of Textbook Example 3.9 

To obtain a very accurate numerical solution, should we use a very small Dt? Say for instance 10^{8} min.
