8.126 This problem involves the determination of the friction factor
in a pipe for laminar and transitional flow conditions. To proceed
with this problem, go to Appendix H which is located on the
book’s web site, www.wiley.com/college/munson.
8.127 This problem involves the calibration of an orifice meter
and a Venturi meter. To proceed with this problem, go to Appendix
H which is located on the book’s web site, www.wiley.com/
college/munson.
8.128 This problem involves the flow of water from a tank and
through a pipe system. To proceed with this problem, go to
Appendix H which is located on the book’s web site, www.wiley.

■ Life Long Learning Problems
8.132 The field of bioengineering has undergone significant
growth in recent years. Some universities have undergraduate and
graduate programs in this field. Bioengineering applies engineering
principles to help solve problems in the medical field for human
health. Obtain information about bioengineering applications
in blood flow. Summarize your findings in a brief report.
8.133 Data used in the Moody diagram were first published in
1944. Since then, there have been many innovations in pipe material,
pipe design, and measurement techniques. Investigate whether
there have been any improvements or enhancements to the Moody
chart. Summarize your findings in a brief report.
8.134 As discussed in Sec. 8.4.2, flow separation in pipes can lead
to losses (we will also see in Chapter 9 that external flow separation
is a significant problem). For external flows, there have been many
mechanisms devised to help mitigate and control flow separation
from the surface, e.g., from the wing of an airplane. Investigate either
passive or active flow control mechanisms that can reduce or
eliminate internal flow separation (e.g., flow separation in a diffuser).
Summarize your findings in a brief report.
