An undeformed specimen of some alloy has an average grain diameter of 0.04 mm. You are asked to reduce its average grain diameter to 0.010 mm. Is it possible? If so, explain the procedure you would use to and the name the processes involved.

A food-services company with a 480 V, three-phase service entrance has the following set of loads:  A 7 ton walk-in refrigeration unit:3 COP of 1.2 and 0.

In class we learned that in order to uniquely identify one of N equally likely symbols, ceiling (〖log〗_2 N) bits of information must be communicated.

At steady state, a refrigeration cycle operating between hot and cold reservoirs at 300 K and 275 K, respectively, removes energy by heat transfer from the cold reservoir at a rate of 600 kW.

When 2 cars a and b are next to one another, they are traveling in the same dierection with speeds va and vb, respectively.

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.
