True or False: Galvanized steel pipe can withstand moderate freezing.

In fully-developed laminar pipe flow, consider the rate of work done on an annulus of thickness dr (hint: consider, for each face of the annulus, rate of work = power = force * velocity).

What is the function maintenance? List some important steps for vibration monitoring based maintenance.

Various factors to be considered in deciding the factor of safety?

Work-producing devices that operate on reversible processes deliver the most work, and work-consuming devices that operate on reversible processes consume the least work. a) - True b) - False

A vehicle has individual wheel suspension in the form of helical springs. The free length of the spring lf = 360 mm and the solid length ls = 160 mm at a compressive force of 5000 N. The shear modulus G = 80 GPa.

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
