Repeat the analysis in Problem 22. 8 using cooling water as described in Problem 22. 9.

Data from problem 22.8

 Consider the Dowtherm A loop described in Section 22.3. For the options involving multiple pumps either in series or parallel, determine the configuration that provides the maximum scaleup capacity. What are the temperatures of Dowtherm \(\mathrm{A}, T_{3}\), and \(T_{4}\), and the maximum percent scale-up?

Data from Problem 22.9

 Repeat the analysis in Section 22.3 for the case when cooling water is used in the heat exchanger in place of boiler feed water. The cooling water enters at \(30^{\circ} \mathrm{C}\) and must exit at \(45^{\circ} \mathrm{C}\).
