Textbook Question
Chapter 19, Problem 19.27PP
Forthe conditions shown in figs. 19.719- 19.10 0, complete the design of the duct system by specifying the sizes for all duct sections necessary to achieve a system that is balanced when it carries the flow rates shown. Compute the pressure at the fan outlet, assuming that the final outlets from the duct system are to atmospheric pressure. When an inlet duct section is shown, also complete its design and compute the pressure at the fan inlet. Note that there is no single best solution to these problems, and several design decisions must be made. It may be desirable to change certain features of the suggested system design to improve its operation or to make it simpler to achieve a balanced system.

Find the loss in total pressure for each run in the simple duct system of Fig. 1, using the
equal-friction method and in English unit. The total pressure available for the duct system
is 0.12 in. wg (30 Pa), and the loss in total pressure for each diffuser at the specified flow
rate is 0.02 in. wg (5 Pa). Duct fittings are listed in Table 1. Assume the duct dimeter in
run 1 is 10 in. and the rest are 8 in. Does the duct system require any adjustment?
