Textbook Question
Chapter 9, Problem 9.25P
The pressure transmission line response equation of Equation 9.23 can also be derived by considering the forces acting on a fluid element within the connecting tubing (12). Develop a model for the system measured pressure response based on an applied pressure force, shear resistance force, and restoring compliance related force through Newton’s momentum (second law) principles. Refer to Figure 9.35.

Problem 9-4: The pressure fluctuations in a pipe filled with air at 20°C at about
1 atm is to be measured using a static wall tap, rigid connecting tubing, and a
diaphragm pressure transducer. The transducer has a natural frequency of 100000 Hz

dynamic error? Plot the frequency response of the system.
3. Microfluidic channels will need to be fabricated on a key micro-scale sensor used by aerospace
industries. Before running machining tests and analyzing machined quality, preliminary efforts are needed
to evaluate selected materials and factors affecting machining process¹. Three material candidates have
been selected, including 422SS (stainless steel), IN718 (nickel alloy), and Ti64 (titanium alloy) with their
measured tensile properties and equation of true stress-true strain relationship used listed below. Tref25°C.
Specifically, three factors will need to be evaluated, including different materials, temperature, and size
effect. Please calculate true stress values for true strain ranging between 0-3 for each case listed below.
