An insulated steady-flow mixing chamber has two inlets and 1 outlet. At inlet 1, the mass flow rate is 0.08 kg/s. At inlet 2, the mass flow rate is 0.15 kg/s. The average velocity at the outlet is 12.84 m/s. The area of the outlet is 0.01 m2.

Pressurized steam at 400 K flows through a long, thin-walled pipe of 0.6-m diameter. The pipe is enclosed in a concrete (stone mix) casing that is of square cross section and 1.75 m on a side.

Consider an ordinary mercury-in-glass thermometer as a measurement system, and indicate which parts of the thermometer correspond to the components of a measurement system. (detect, transform, output)

In the contemporary approach to control systems, benefits of continuous monitoring include which one of the following?

The Reynolds number, rhoVD/μ is a very important parameter in fluid mechanics. Determine its value for ethyl alcohol flowing at a velocity of 4 m/s through a 2-in.-diameter pipe.

Work done by a system during a process can be considered as a property of the system. a) True b) False

When the compression process is non-quasi-equilibrium, the molecules before the piston face cannot escape fast enough, forming a high-pressure region in front of the piston. It takes more work to move the piston against this high-pressure region.

hypothetical A-B alloy of composition 40 wt% B-60 wt% A at some temperature is found to consist of mass fractions of 0.66 and 0.34 for the α and β phases, respectively.

10. Which of these requires a wheel alignment after replacement? A. Struts B. Shocks C. Both
